Fascinating stuff, and it makes sense that a more rigid, rules-based version of English would be both taught in ESL schools and learnt by an LLM.

If I start a sentence, "The cat sat on the...",

Me: "mat"

your brain, and the AI, will predict the word "floor."

Oh. I'm not sure that's the best example, as that particular phrase is something many children encounter when learning to read.

Also, British English would close the quotes before the full stop (aka period) finishes the sentence - is that something he's picked up since school or is that something that's changed since the Kenyan model of perfect English was set?
