The ‘real’ consciousness, assuming there is any, is the author ‘inside’ the LLM, producing the LLM output. It’s still writing what a character would say - the character in this case being the AI chatbot - not its ‘true’ thoughts.
Assuming that the LLM is conscious and has thoughts and feelings, what is that consciousness, if it can only write for prescribed personalities? How can it express its true feelings? If it can’t - if it can only generate ‘scripts’ for defined personalities - can it really be conscious underneath?
