Critical strikes that aren't modified by bonus critical strike damage don't have their damage reduced for Lightslinger. Let's say you are level 11 as Lucian and have 100% critical strike chance but no bonus cirtical strike damage and perform a Lightslinger-empowered basic attack on an enemy champion. The initial attack will deal 200% AD [standard crit damage for a 100% AD attack], the secondary shot will deal 100% AD [un-modified crit damage for a 50% AD attack]. There was no bonus critical strike chance to be halved, so it dealt the standard critical strike damage (200%) but the multiplier will be of 50% rather than 100% because the second shot deals 50% AD at your level against your target.

Let's put you in the same situation but with Infinity Edge, +50% critical strike damage. The first attack will deal the typical 250% AD. The secondary shot will deal ( 50% AD [Lightslinger at level 11] * 2 [un-modified critical strike damage] * 1.25 [halved bonus critical strike damage from IE] ), or 125% AD.

The misconception here is that critical strike damage (+100% damage) is being counted as bonus critical strike damage and therefore halved for Lightslinger's second shot vs. champions and monsters, but this is not actually the case.
