When creating new lints that don't fit in the old lint categories, I usually go through kinda samey hoops of creating new files and copypasting LateLintPass/EarlyLintPass boilerplate from existing lints. Is there a script or something I can use to generate them for me (if that's possible?). I didn't find anything related in utils.

Nope, this has to be written by hand ATM. It could be an addition to clippy_dev though. I can think of a ./util/dev new_{late,early}_lint <LINT_NAME> which then creates a file with the boilerplate for a lint with the name <LINT_NAME>.rs and the lint definition in it.

A good addition might be a hi test file with an empty main method and a TODO comment asking to add things that should (not) be linted.
