The FAA has previously cross-checked federal social security disability benefit records, those pilots went to jail.

The FAA has access to all federal records. I have not heard of them checking VA records probably because of the optics of witch-hunting veterans during a war. But that doesn't mean they'll never do it.1

You're in a tough spot, now that you're getting VA bennies for OSA you'll have a very uphill battle with the FAA. There are many things you can have a VA rating for and still hold an FAA 1C but OSA is not one of them.

You may need to resolve the OSA, or you may be able to fly using one of those portable forced-air contraptions to sleep at night.
