We have a Landlock (formerly Bubblewrap) Linux sandbox due to an LLM. It sat unfixed on our roadmap for almost a decade. I and at least one other maintainer (as well as several LLMs) reviewed every line of code.

Homebrew has never been better performant, secure, tested, linted and typed. I understand the LLM dubiousness (I used to share it myself) but we’re the type of project where it’s very easy to get agents to do sensible end-to-end testing and review a nice language (Ruby). Just us on our outputs, not just our inputs.

One of our former maintainers was in high school when working on Homebrew. I’m sure many people would have found that worrying. His code was great, though (I reviewed most of it) and he made the project better. Same ultimately with LLMs. Your mileage may vary.
