So this seems to be an issue against using AI to generate "original" content (yes, the quotes are deliberate).
And I agree, that's wrong.
But what about an AI editor/proofer? We already have tools that can analyze for spelling and grammar and not only are they widely used, it is considered silly NOT to use the spellcheck in your editor of choice.
How about an AI based editor that can give advice on a more meta level? Something like, the story bogs down in description on page 3 when it really needs to be action, action, action at that point. You seem to hint at a mystery with this character but they it never gets resolved. Did you mean to do that?
While I don't think current AI is up to that task, I would also be ok with an AI editor giving that type of advice.
