I assume the GP meant "scale of codebase complexity" – which is orthogonal to whether something is "web scale" (ie. everything Google does).

Isn't the Google codebase infamously a monorepo with billions of loc? That seems like it fits "scale of codebase complexity" as well as "web scale"

It's a monolithic repo, but not a monolithic codebase. It contains many many separate projects, libraries, and applications. There's a lot of code reuse, but it's not like you have to wrap your head around the whole thing.

Yes, but much (if not most) of that codebase is in C++.

How do you check out a project like that?
