Nope, they use core text, same as me. And they do support ligatures, if the font has them. 1ms delay sounds like a reasonable heuristic.

I've never seen Terminal.app use ligatures. I just tested with Lucida Grande, which has ff/ffi/ffl ligatures, and Terminal.app didn't use them at all (it just spaced the characters out on a fixed-width grid). Can you give some examples where Terminal.app will use ligatures?

It uses ligature level 1. fi, etc., are level 2. Try a font like FiraCode to see ligatures on mostly punctuation like ==.
