I'd say it's about the same as other issues in relationships. People ain't perfect. I have a few habits which don't really resonate with my partner at all. And I see other people discuss other stuff as well. The amount of partying someone does, friends, kids, doomscrolling and TikTok addiction, chores, leisure time, relationship to someone's parents... There's a million things to fundamentally disagree on.

Somehow you need to work it out. Talk. Make up your own mind, think about where to compromise, what are hard limits for you. And what's more important to you. That thing or her. And where do you all want to go. And then find a effective ways to talk. Seems to me what you've been doing is talk, but from the description, it doesn't seem like it's all that effective.

I personally don't think policing someone's work is the job of a spouse. I'll ask my partner what's up with their job, take interest, empathize... But I don't tell them how to do their work. On the other hand I have expectations for personal life. I wouldn't like it at all if someone brings AI slop into the shared living room. I might be able to compromise on some of it, especially if I disagree on the way to do it but there's no bad consequences. But there's hard no's for me. And you do you.

I think most important is to come to some kind of agreement which makes everyone comfortable at least to some degree. If you wanna make the relationship work, that is. But I feel if she's saying one thing but does another... There's still some things to work out. Either you're not really communicating and she just says yes to make you stop. Or she's struggling to pull it off. (Might not be easy at all to quit AI?) Or you both have different opinions and avoid conflict.

Edit: Maybe another option is to remove your own opinion for now, and just listen for a while. Find out what she wants. Where she's at and where she wants to go with this? Maybe she feels like she's okay with AI? Maybe it's some proxy for something else? Maybe she wants to quit, maybe she doesn't? I feel that's all important information for any further considerations. (I mean your post is mainly you writing down what you want. That's perfectly alright. You also write what she does but there isn't really anything about what she wants. So we're missing a substantial chunk of the equation here.)
