I try to understand WHAT all code does rather than exactly HOW it does it. Large scale design choices, how it is tested (and that it is) etc.
Even if you have a 20 file 5k line change set, it's still not impossible to just grok what's being done, what the purpose is, and what it works like on a high level.
LLMs don't change the fact that such a review is difficult, but I'm more confident that there are no hidden off-by-one issues in 5k lines of LLM code than in 5k lines my colleague (or myself) wrote. So it's a welcome change in reviewing to do it on a higher level.
