Regarding Kiel's at bat where the ball hit his hand, the possible calls were ball, strike, or HBP.
They ruled that he moved his hand toward the ball intentionally and called it a strike per NCAA rules.
MLB would have ruled it a ball.
Hit By Pitch, Stay Here! Rule Differences & NCAA StrikeQuote:
In college, such as the St Mary's-Pepperdine game, NCAA Rule 7-4-i states that, "A strike is awarded if the batter is judged to intentionally make a movement to be hit by a pitch, regardless of where the pitch is located; or allows themself to be intentionally hit by a pitch that is not thrown within the boundaries of the batter's box unless it was not possible to avoid being hit."
In MLB or MiLB, though, this same play would result in a ball added to the count, pursuant to OBR 5.05(b)(2), which adjudicates the play differently: "The batter makes no attempt to avoid being touched by the ball...If the ball is in the strike zone when it touches the batter, it shall be called a strike, whether or not the batter tries to avoid the ball. If the ball is outside the strike zone when it touches the batter, it shall be called a ball if they make no attempt to avoid being touched."
