My cousin was on Fearless at the time. And they did unload LR,s with the bulk of the Marine force. If you go back over any of the documentarys of the conflict you can see plenty of LR,s in them. Including the 101 pictured in Stanley as the Marines and Para,s march in. There is even a 101 on a hillside in the falklands that was dropped in order for one of the few Chinooks to gain height over the otherside.
