If my child had a learning disability theres no way they could get away with the do nothing approach.
Sadly this isn't the case in many schools (not saying it is right, just saying that it happens all too often at least where I live). I can hardly believe some of the stories from one of my friends who's child has low vision....
In addition to academics we've tried to challenge the kids in other areas which is easier to control/achieve on our own. Things like music, drama, the arts, team sports, individual sports, clubs, 4H, scouting, etc. might be potential things to consider. My DS in particular isn't particularly sporty but we keep him in sports for many reasons beyond the exercise.
Hope you can get some traction with the school. It can be a challenge.
