Unsure Ump on D3k

[alblueboy]

NFHS
Ball field is extremely dry and dusty. 1st base is open.

1 ball..2 strikes on batter. Next pitch is low and a cloud of dust arises on impact with additional dust as the catcher attempts to catch it.
Batter swings and runs to 1st. No play is attempted and the ball is returned to the pitcher in the circle.

BR thinks she is out and steps off. Coach at 3rd wants a ruling on the D3k. Time is called and PU goes to confer with FU. He states that he didn't see it. After a discussion it is ruled that the ball hit the ground first before the catch.

Question
Should BR be called out for a LBR violation??
