[Landlord- US IL] Repairing Nail Holes

We just had new tenants move in and they are requesting a bunch of repairs. One of which is that there are small nail holes from pictures in the bathrooms. This will cost $600 from our contractor because he has to repaint the entire bathroom since he doesn’t have the paint color match. Do I have to get small nail holes patched? I know it’s nice of me but to do but they are being rather nit-picky with everything they are requesting.
