The buhddists put in the legwork ages ago: the line is if the organism has a chemical stress response to stimuli.

Like could an motivated human torture it and could it try and escape the situation.

But that's assuming the organism/thing can move. easy counter-example: a paralyzed human being.

How is that a counter-example? A paralyzed human can still exhibit a chemical or physical response to an external stressor or stimulus in general, such as body temperature, sweating, neural activity, etc.
