Doubt it. If you needed an LLM to launder it it's surely not trivial. Trivial is any well known code pattern for example.

"for(int j=0; j<ARRAY_SIZE(a); j++) total += a[j];" - you could copy paste this and more out of leaked Windows source code and it still wouldn't be a copyright violation. But beware that a sum of a large number of trivialities can be not trivial.
