Liandry's isn't necessary for taking 1/4 of a squishies HP. Also the ult alone deals 600 damage in the end, wich is pretty much 1/4 of a squishies HP. You burst them too fast that Liandrys would be noticable. Rylai's Crystal Scepter  will slow champions on-spell-hit but the slow only lasts 1. 5  seconds while the DoT occurs over 3 seconds, so only first half of DoT will be doubled. Also it's "of the current health", BaB is "of the max health".

My AP Kog build allways builds MPen boots, void staff, rabadons and arch angel aswell rylain's. Those are definitly the items you must have. You could go for a RoA instead of arch angel, but I stopped doing this, since it weakens your anyway low early game even further. As last item I'll buy a Nashors, Unholy or Hourglass.
