OK, good read for me here. Based on your feedback and some research, I think I should have use ‘sociolect’ for both in that I was less complaining about ChatGPT’s unwillingness to use, say, finna, in a sentence, and more complaining about the vocalized accents. Anyway good catch, thanks!

Sociolect is the right term for a dialect used by a particular social group. A related idea is "register" when multiple related and mutually understandable standards exist, and are used in different contexts.
