I would suggest using AI in a particularly constrained way; and specifically the Google search AI.

Use it to find websites with writing advice in particular subjects, and then copy that writing advice into the AI and ask it to use that (and only that) to judge how well your writing adheres to that advice.

AI is trained on everything on the web, and that makes its judgements bland, because the average of everything is not ever great. So do not use it as a judge of quality; the best it can do is notice when you deviate from "average" and then tell you that your writing is not good because it is not average.

But what it is reasonably good at is following rules you set down, and then checking to see if your writing follows those rules. That is a way you might use AI to help you improve your writing; as a coach or tester trained on a specific "How-To" website.
