No interference on the play you described. There has to be a quality throw. The possibility that the presence of the batter-runner outside the lane caused the bad throw is not considered. Without a reasonable throw, you don't call interference even if the ball hits the runner. Example: bunt two-thirds of the way to the mound, F1 picks up the ball and fires it 15 feet short of 1B, and it hits the batter-runner running outside the lane. Neither F3 nor anyone else had a chance to catch the ball. No interference.
