Libraries can be audited. LLM generated code cannot.

Edit: to clarify, it is impossible to audit all LLM generated code across a number of projects, that would replace a single library. It simply won’t happen, because there will always be a non trivial number of users who will copy and paste code without inspecting it. In contrast, widely used open source libraries may be audited by a small subset of their users, and the rest would benefit from that.
