This is one of those rejoinders that tries to be clever but really, really isn't. The "intern as fake CEO" is left holding the bag because it's their signature on contracts and other legal documents. The idea of puppet CEOs to fraudulently dodge accountability existed well before LLMs became a thing. Courts see right through that kind of scheme plus the "intern" is likely to turn coat against the mastermind to save their own skin at the first sign of trouble.
