ar-nil-terminate does a shallow copy, but ac-niltree does a deep copy.

Insane. I'm bummed I haven't noticed this before :( Has it come up in the past?

I also just noticed: It is _utterly_ insane that niltree converts () to nil, while nil-terminate does the opposite.

It's called "tree" because it recurses on the car. In other words, it traverses sublists. As for why it's called "nil", well, I guess that's because you can't use () in the name without using || quotes. I'd call them "nil->null" and "null->nil". Or perhaps "arc->racket" and "racket->arc".
