One question I would ask is whether or not the CEL ever came on during this ordeal, or did the oil pressure "gauge" ever go to zero? (Remember that since it is an '05, it is not a real gauge but only an idiot light with a needle.)
If not then it is probably ok, since the engine never lost oil pressure. As long as there was enough oil in the pan for the pump to suck up, nothing should have been damaged in the short term, since oil pressure would have remained normal. Of course you wouldn't want to run very long like that.
True story (non-Jeep). On vacation several years ago in our F150 with 125k miles on it, we experienced sudden PCV valve failure(unknown to me at the time) which caused our oil consumption to go through the roof. Checked the oil a week or so into the trip and found it 3.5 quarts low out of 6 qt capacity. But no warning light, so we never lost pressure. Filled it up with oil, changed the PCV valve, and we're still driving it today with 213k.
