Although the citation regarding umpire's interference is correct—the only two types of umpire interference (plate umpire interferes with catcher's throw/play after a pitched ball or base umpire hit by a fair batted ball before it passes an infielder [not including the pitcher, provided that it is not interference if it DOES touch the pitcher before the umpire]) do not apply here as the umpire was working outside the infielders—the "Time" question is fairly technical.
And the answer to this question is to look at the play holistically: the game situation when this occurs is none out and none on, meaning that the only runner to pay attention to is the batter-runner, who, on this play, safely advances to, and remains on, first base.
NCAA Rule 6-5-d pertains to calling time when a potential injury occurs (umpire getting struck by a line drive may or not may not be an actual injury, but it could be a potential one), and states, "Time shall be called by the umpire and play is suspended when an umpire or player is injured, except that if injury occurs during a live ball, time shall not be called until no further advance or putout is possible; If a player is injured and cannot proceed to the awarded base(s), a substitute runner may be used to complete the play."
Thus, from a technical rulebook standpoint, the "Time" call is covered under NCAA 6-5-d, though from a more holistic point of view, it hardly matters whether or not "Time" is called—the result of either calling or not calling time is that the batter-runner advances safely to, and remains on, first base.
