tl;dr - The development LLVM libc is under the LLVM umbrella in the open.
That makes LLVM libc also open for collaboration by default :)

That said, it will help if you can elaborate more about what you mean by
"collaboration". LLVM libc is in early stages. However, few downstream
users have already started using the parts available in production. Our
focus areas for the near future are the pthread library, stdio and
finishing the math library.
