I think they expect you to also use an LLM to review, and I bet they are doing exactly that when asked to review someone else's code.

That gets you 90% the way there. So, it it only really works if you accept the cruft and the risks associated with that last 10%. Been doing this day in a day out for the last few months and no matter how much and how good we get the automated reviews, we still can't skip the manual ones.
