What grosses me out is the very idea of torturing anything at all. Even the word "torture" itself. I'm not sure what this is for or how it helps at all. This crap belongs in the gutter.
Doesn't require aliveness, doesn't require anthropomorphization, just requires maths and empirical data. If your premise is "vectors can't have that shape", well, mathematics disagrees.
edit/note: sentiment classifiers have existed for ages before LLMs were ever invented. Obviously a task that machines could already do didn't suddenly become impossible with the invention of LLMs ;-)
I see the AI torture chamber more like a satire, making fun of people who think AI can somehow "feel" "pain". Someone who'd rather believe in pure fiction than face the actual harm to real humans that AI is causing right now.
