My instinct is it is a distinction without a difference in this context. i.e. if deductive is "I watched the cue ball hit the 8 ball, therefore, the 8 ball is moving" and abductive is "the 8 ball is moving towards me, therefore the cue ball must have hit it. I cannot claim to have deduced this because I did not observe it", LLMs cannot observe the situation, so any deduction (in the binary induction/deductive sense) must be done by abduction.
