how do you do a pullcounter against a southpaw?

You don't pull counter a southpaw. Doing a pull counter on a right jab is useless.

Its actually easier on a southpaw, Most southpaw but shoulder rolling a southpaw is a no-no for me.

Shoulder rolling is even more useless against a southpaw. I agree with that. Blinds you to the right hook, and the angle for a straight left hits home.
