Also why he bring up Vader at all when Vader DOESNT EVEN APPEAR ON Andor at all. Like hes expecting Vader to literally know everything and teleport just to force choke a honestly pretty low ranking imperial officer.

Like tbh Vader would not have any appearances that show him directly condone SA because Disney probably wont want their le epic toy figure that ends up in jedi heaven to do that, which is why vader/force users dont really show up in Andor! It would cause a huge tonal dissonance unless they are handled carefully.
