If you prompt LLMs to use poor spelling and grammar, they will.

But can they do it convincingly?

if you've been on the internet forums for 20 years, you'll discover that real life user's spelling mistakes are borderline unconvincing :/

so in that way the llm has a very low bar...

Yes, especially if you give them a sample.
