B just scores right near the end of the game to go up by 1, with a few seconds left. A2 receives the inbounds pass after the basket, and sees B1 standing by sideline getting last-second instructions from the coach. A2 takes a couple of dribbles towards B1, who happens to have one foot on the sideline, facing the coach. A2, without any other pressure, bumps into B1 and goes down. So, B1 does not have LGP, by rule (not facing the opponent, in bounds, both feet on the ground, etc.). B1 is stationary.

Is your call a block on B1?

rule 10 section 1 Art 8 NCAA best describes this
A dribbler shall neither charge into not contact an opponent in the dribblers path not attampt to dribble inbetween two oppnents or between an opponent and a boundry, unless the space is sufficent to provide a reasonable chance for the dribbler to pass through with out contact.

and to conclude the other part of the argument
art 10
when a dribbler has obtained a straight line path, the dribbler may not be crowded out of that path; when an opponent is able to legally obtain a defensive position in that path the dribbler shall avoid contact by changing direction or ending the dribble.
So the defender in the original OP is legal until that foot goes out OB
