If they're okay with vibe-coded code, they should be fine with vibe-coded reviews too. You really only should be in a situation where you have more responsibility over your reviews than other people have for their code if you're in charge, and if you're in charge, just ban the practice.
The problem is other people/teams making PRs to your code that you then have to maintain or fix later. It’s in your interest not to half-ass the review, creating an asymmetric amount of work for you vs them.
