The whole point of using AI is to generate more code more quickly. If you cant keep up, then step out of the way. Some people think being a reviewer is a privileged position. Well now you've got your work cut out for you.
Ultimately the solution will be to get rid of reviews and reviewers, and put the responsibility for the code on the "author" (prompter). If you're using AI to generate code you're already mostly just a reviewer, putting more reviewers on the same code just slows everything down. What's needed is more accountability.
