What would it mean for a human to feel the passing through our bodies of 100 trillion neutrinos every second?

My point is that there are things we cannot "feel" either. Why should consciousness depend on certain feelings and not others?

Because we don't have a sensory organ for neutrinos. LLMs have no sensory organs, they just emit tokens.
