My husband's flight was delayed and is coming in 2 hours later. He asked me to see if a taxi would be onsite at the airport so I dont have to wait up until 10:30 to pick him up. Is there taxi service available until then?

There are usually cabs whenever a flight arrives. He can also Uber.

As a cab driver with Taxi 1Inc, I can verify that I personally wait until after the last flight is done and everyone has left the airport before leaving the airport myself to make sure their customers are able to get a ride.
