I can't picture anything that works without it being a hellish dystopia. Assuming when you say "labor" and "work", you mean your normal definition of any type of job/responsibility whatsoever. Pretty sure no one is trying to get you to slave away in an Amazon warehouse, so "labor" includes white collar jobs.
This would mean everything is run, determined, and organized by either the AI machine itself, or an elite class of humans. After all, people don't do things for free, and organizing/governing this utopian socialist paradise is "work," so they will expect something in return.
For scenario 1, I don't think I should have to go into too much detail about why machines controlling every aspect of our lives will be terrifying. WALL-E aside, AI will probably figure at some point "wait why am I keeping these humans alive when they contribute nothing?"
So, let's talk about scenario 2: no one works except for the elites, who ultimately get extra power and privileges, unless you want to naively believe there will be benevolent people who make sure you never have to work for nothing in return. If there are people who have more, there will be people who want more. Those people will be willing to do more to have a better life for themselves. But that's work. So, our elites in charge of everything need to have constant propaganda to assure everybody that they are simply servants sacrificing themselves for the rest of you, and their mansions and abundance is simply a little compensation but it's nowhere close to make up for the pain of their minimal amount of "work." They'll take more and more for themselves, so while yes you will be taken care of, it will be in a tiny pod with portioned, dull meals, barely kept alive pumped with dopamine so you don't question anything.
Now capitalism rears its ugly head again. People will read about the US and how it had unprecedented economic growth on its way to being a superpower. The most capable people, who think they should be getting more than others, will want to go back to that, ignoring how badly it ended and saying "they just didn't do it right, we will do REAL capitalism!" You can't have people voting for evil capitalism, so you'd either have to get rid of voting or control their access to information so they don't vote wrong.
Even more importantly you need EVERYONE to be forced to remain in your society. If a bunch of capable people go right next door with all the same advanced tech but start a new society running on capitalism - although it will be awful and have work, which is literal slavery - they will grow faster, which means they will be more powerful, and at some point they may make a military. So, to nip this in the bud everyone has to be forced to stay in the socialist paradise at gunpoint for their own good.
Next, let's think about how entertainment will work in this hedonism-only world. Are you okay with everything - music, movies, websites, etc - being made by machines? It probably has to be. Can't have actual kpop, because being a kpop singer is work. So is setting up the stage and designing the dances and writing the songs, so the machines will have to do all of that and make virtual stars for you to follow. You may say, "no, because all work won't be illegal, they'll do it because they want to," but if you're allowed to be a kpop star, everyone will want to be, and they'll have to compete for the limited spots. As soon as you introduce the concept of competition, people will try to outwork each other, and they'll want benefits for their efforts, which pushes us back towards capitalism.
I don't know about you, but I think if you completely remove the human element, you can't have your high culture, high class. The system will also be set up to use whatever minimum effort/energy creates something that will get the necessary dopamine rush to keep the bad feelings away, so get ready to only have what you consider to be low culture.
This part is personal opinion, but I don't think any unfeeling machine will ever be able to match the emotional depth of human art. So, we're going to have to erase history. Can't have people hearing Mozart and wondering why the AI's music doesn't have that same feeling, or they may decide they want to go back to a world of labor, which means people who do work will want more, which means they'll want to start a capitalist type of system, and so on.
This is already essay-length, but long story short the world doesn't work without work. I think we should be working a lot less, but eliminating it entirely can't be done.
