In a dogfighting scenario, the only teamwork the crew uses is the pilot pointing the lib belly in the general direction of the aircraft. In anything but a shredder lib, that requires considerable skill, to be sure, but teamwork? Not really. If you bring up the 2 person lib thing, then pulling 2 ESFs takes just as much coordination. I'm not saying that ESFs should be insta-win buttons against liberators, but properly loaded out ESFs (aire nosegun, AB or air secondary) should have a fighting chance to take down the ESFs when they have surprise if there are 2 of them, even if the pilots have relatively little skill* and a skilled solo pilot should be able to take down or drive off anything but an exceptionally skilled or lucky lib crew unless they make a mistake. *and remember, skill is relative in the ESF game, a noob pilot still probably has hours of practice under their belt, and someone with a decently certed out plane: days. With the high barrier to entry for ESFs, even those noob pilots you feel justified schredding into tiny chunks have probably devoted a fair bit of time to flying.
