LOC is for when one has an ILS system but does not utiliZe the glideslope, either because it is unserviceable, it is a back course, one chooses not to for training or other purposes or because the aircraft's systems are unable.
LLZ is for a standalone localiZer system without glideslope. These do exist, and in fact existed before the ILS, and the system was invented by that chap educated in Californiashire.
But you brilliant chaps across the pond knew all that, and the Yanks have not a thing to teach you.
As for 'aluminum', that was coined by a British fellow, Sir H(arr)umphry Davy, as he wasn't fond of 'alumium', which he first called it. However, that usage annoyed other British fellows, because they preferred all their 'ium's in a row.
tottigol, kindly let me have a 'harrumph' out of you.
