Only if you want to fly to LA and then JFK.
CZ will eventually get the crew back to the airport and fly you onward to JFK or arrange for you to be carried on other airlines' flights (though that will be hard given lack of available seats).
This really has nothing to do with DL as you're a CZ passenger on a CZ ticket. DL cannot do anything for you.
