Correctible Error?

[TexasRef]

1-1/2 min. left in a 1 pt JV girls game. Free throw made, ball handed to A1, A1 kneels down to tie shoe, co-official (U) ask if she wants a time out, she says NO, she is eventually called for a 5 sec. violation. (VS coach) not JV coach steps out on floor during time out and drills officials trying to to get (R) to go against the (U). Officials stayed calm, moments later, (U) goes to VS coach and admits he made a mistakes. I know we shouldn't have allowed the VS coach to get involved. Next the VS coach inquires about the call again, wants (R) to reverse call as a correctable error. I don't think play had resumed. I know we normally stop play on dead ball and allow/encourage players to tie shoes, but . . .
Q: Was this actually a bad call or just a mistake in judgment?
Q: If bad call, is it a correctable error by (R)?
