You can make an LLM sound very natural if you simply ask for it and provide enough text in the tone you’d like it to reproduce. Otherwise, it’s obvious that an LLM with no additional context will try to stick to the tone the company aligned it to produce
Agree. I keep asking LLMs to tell me some jokes from time to time, but never once I've found it's funny. For me, when I find myself burst out laughing from LLMs joke, I'd know we've reached AGI.
