I agree with OP, coach is out of line with that statement. Nothing wrong with him coaching her up on her swing. He may not be correct, but he thinks he is, and it is his job to coach. Not to be negative, and to bring her down, but unfortunately some people are like that.
Like others said, remind your dd that she can hit, and is a good player or there would be no college coach talking to her as a sophmore. Slumps happen, and she will come out of it. My DD is in the midst of the worst hitting of her life, but I am starting to see signs of her swing looking better, and more confident the last few games. The only few balls that she has managed to get out of the infield lately, of course, have went right to someone. It happens.
