It's only "statistically generated" in the same way that your brain is just "neurons firing." That's the low-level description of what's happening, but on a higher level, it's correct to say that it's being smug.
It's not correct to say that it's being smug, because when people are being smug, we do it for a purpose - e.g. to signal higher social status or superior knowledge.
A machine has no such imperative, so what you call 'being smug' is statistical mimicry.
I suppose the model was trained in such a way, the smugness is a facsimile of reality. Other models offer concise, direct answers without these idiotic qualifiers.
