Unfortunately there does not appear to be an entry for Laglass Hill in the Ordnance Survey Name Book (1855-57).
Gaelic lag ‘hollow, crevice’ Gaelic glas ‘grey, green’
Michael Ansell identified Laglass Hill as Gaelic An Lag Glas ‘the green/grey hollow’ and considered it ‘may have orginally referred to the boggy area of Star Bog‘, to the south-east of the hill [1,2, 3].
However, to the west of Laglass Hill is Dingle Brae which takes its name from dingle ‘hollow and brae ‘brow of the hill’  . The hollow in question lies between Dingle Brae and Berry Hill which fits well with another of Dwelly’s offerings Gaelic lag ‘hollow between to knolls’ .
Laglass Hill sits at the top of this hollow , i.e. ‘hill at the green/grey hollow’.
