You seem to assume that the code review tool can do everything that a human code reviewer can.

On the other hand, a machine will not get tired or bored where a human most definitely will if the diff is anywhere near that 500 lines

I disagree. I regularly review PRs with more than 500 changed lines/20+ changed files. I read every single line. I put the same amount of effort into reviewing code as I do writing it; every software engineer should.
