Our code review process involves a reviewer explicitly taking ownership of the PR, and I think it's a reasonable expectation with the right practices around it. A good reviewer will request a PR containing 1000s of lines be broken up without doing much more than skimming to make sure it isn't bulked up by generated code or test data or something benign like that.
And just to add to this, at least in Google generated code is never seen in a code review. That’s all just handled by Bazel behind the scenes.
