I concur with your description of the "feel" of an aircraft in #1162.
In Normal Law - there is no such feeling of how much control surface deflection was required to satisfy your request.
Can't find any trim for roll in the 'bus manuals
Correct.
In Normal Law, it is trimmed automatically by deflecting the ailerons sufficiently so that at stick release there is zero roll rate.
In ALT LAW it's like a Boeing in roll. Stick deflection demands a proportional aileron deflection. The only trim available is rudder - to yaw the wing sufficiently so that aileron deflection is not required to hold the wing level. The roll rate is faster.
In Alt Law, Pitch control "feels" the same as Normal Law - you select a delta g, it changes attitude and stays there on stick release - automatically trimming as the speed washes off.
