The prohibition after the Butlerian Jihad was "Thou shalt not make a machine
in the likeness of a human mind."
Emphasis added. Not "Thou shalt not make a machine mind". You have to read the text carefully.
A portrait of a person is a likeness of a person; but is not a person or even on the way to being one. Even a cartoon can contain a "likeness" if you recognise the person parodied in it.
I do not regard chatGPT and LLMs as "having a mind" at all or even being on the way to having one. But a likeness, an imitation, a mockery, a parody of a mind, yes that fits.
