Yes, you are correct, and that's a really good way of describing the significance of their technical contribution. Still (as you know), there were a few other pieces the OS needed to truly replace Windows that GNU did not provide - BASH and X.org being two - but the operating system definitely would not be what it is today w/o GNU.
Interesting that you bring up LLVM. Linux's "cousin", FreeBSD, is in the process of swapping their entire toolchain out from GNU to LLVM, quite successfully so far.

I'm honestly thinking to move for a period to FreeBSD just to see the cons and pros even because I enjoy the BSD license better than the GPL
