While I don't agree with running on an empty sump, I doubt any damage was done.
When I was a kid my grandpa had a friend who every year changed his oil in his boat by removing the copper line from the back of the mechanical gauge, placed it into a bucket and started it up.
He ran the engine until the oil stopped.
And we worry about adding oil when the dipstick reaches the "add" mark.
