The question of whether AIs really do "feel" (what you seem to be addressing, through the "psychopathy patient" reference and talk of sentience) is interesting, but is it where we draw the line? Data in Star Trek can't feel, or even laugh, but he comes to be seen as a person. If we set aside the unsolved problems in robotics, embodied AI, etc; aren't we already "there" when it comes to Data's mind? If so, then AIs are conscious.

Data passed Picard's "consciousness" test by expressing awareness that he was in a hearing regarding his personhood, and explaining what the consequences of that hearing could be for him. Isn't LaMDA already there?

Turing isn't a test for consciousness. The tests we apply to animals (can they recognize themselves in a mirror? can they understand their surroundings well enough to solve puzzles like crows?) are very solvable problems in AI. To me the real question is: once AI can do all those things, how can we justify calling them unconscious? A "hunch"? No matter what test of consciousness we come up with, AIs can be programmed (or learn on their own) to solve.
