Your poor DD - it's so difficult for kids with LDs! Tell her that it wasn't personal - the school's mission is to be profitable and meeting her needs would not be profitable. Private schools don't have the same obligations that limit public schools so they can keep out "expensive" kids. Her best bet would be to either find a good gifted program at a public school with a solid special education department or a 2E private school. I toured a couple of great 2E privates a decade ago for my oldest and they got it. Of course, they were about twice as expensive as the prep schools.
