How would you go about reviewing a PR like this? AI is red herring in discussions like this. How the change was authored makes no difference here. I wouldn't.

How would you go about reviewing a PR like this? AI is red herring in discussions like this. How the change was authored makes no difference here. I wouldn't. I'd reject it. I'd reject it even if the author had lovingly crafted each line by hand. A change request is not "someone must check my work". It's a collaboration between an author and a reviewer. If the author is failing to bother respecting the reviewer's time then they don't deserve to get a review.
