That's one way "nz flag in z80" makes sense to me. What else could it mean?

The Z80 part is right, but talking about a flag in the context of the Z80 instruction set it should be quite clear you mean a programming flag not a country flag
whats nz then?
Never programmed on the z80, but a common flag in cpus is Zero or Not Zero (nz), that would be set when the result of an operation is not zero (or zero, depends on the architecture)
For example A = 0 (A being a generic register) would set Z to 1 and NZ to 0, and viceversa for A = 1
I believe it isΒ nonzero ("jump if not zero" iirc)

There's no NZ flag. There's the regular Z flag like in most processors. NZ is the condition of zero not being set.

It's probably a typo in the question or an actual question by human after seeing something like a JNZ instruction.
I don't know the z80 specifically, but it's probably an assembly keyword for a special bit ("flag") that indicates if the result of the previous operation was nonzero.
Just more LLM lazy bullshit.
