4-41: Art. 2 … A player is trying for goal when the player has the ball and in the official’s judgment is throwing or attempting to throw for goal. It is not essential that the ball leave the player’s hand as a foul could prevent release of the ball.
Art. 3 The try starts when the player begins the motion which habitually precedes the release of the ball.

Assuming no buzzer issues:

When does the continuous motion end, in other words how long does continuous motion apply to a "shooter" who can't immediately release the ball because he and the ball are "locked up" due to the foul.

Double pumps? Triple pumps?

Does remaining airborne have anything to do with it?

When does the motion that habitually precedes the release of the ball end?

Situation #1: Airborne shooter begins motion that habitually precedes the release of the ball, said player is fouled, can't continue said motion, ball is withdrawn, said player, while still airborne, is able to "regroup" (double pump) and then release the ball, which goes in the basket.

Situation #2: "Grounded" shooter begins motion that habitually precedes the release of the ball, said player is fouled, can't continue said motion, ball is withdrawn, said player is able to "regroup" (double pump) and then release the ball, which goes in the basket.
