> By the time the child had grown to an adult I wonder what kind of results their LLM would produce and the degree to which it might compare to what the child (now grown) would answer?

It very likely would not compare. Humans are shaped by their subjective experiences not by incoming data and you cannot know what a subject is experiencing solely through the incoming data (except if you have a theory accurately modeling the mind of the subject which is exactly what we are currently missing).

Your LLM won't experience the subject's heartbreaks, joy, grief, shame, hope etc. It will have heard and be able to talk about those, but it will not give accurate answers about what it felt like. Also it won't be able to predict/model accurately how the subject has been changed by those experiences so it could make very wrong assumptions about what the subject could/would do in the future.
