I don't really build health items on Katarina because I like going by the philosophy of "why not just not take any damage at all?" :P

It really just comes down to your playstyle. Now, you're right when you say that Katarina has low AP ratios. BUT she also has low base damage on pretty much all her abilities. This means that even if your opponent has 0 Magic resist after calculating Magic Penetration and Magic Resist Reduction,... Katarina still does very little damage. So, when you see people building all the big ticket Needlessly Large Rod items, they're hoping that they can stockpile so much AP to the point where they might actually do damage.

Back in the old days, Rylai's and Liandry's were staple on Katarina(not to mention that Rylai's' and Liandry's' passives go hand in hand). But stuff got nerfed so people just stopped using them on Katarina. Doesn't mean it isn't good anymore, it just means that it will never be AS good as it was before.

If you're playing as a burst assassin, I sincerely hope that you will never have to fight a tank. That's more or less the ADC's job since he/she has a <0.5 second cooldown on his/her damage dealing "ability"(auto-attacks). As an assassin, you should be targeting high priority carries who have probably been stacking damage and not building defensive items. Keep in mind that ANY damage dealt to a squishy is a lot of damage to them. That being said, you could probably kill their squishies with any kind of items you want, it's just the matter of how efficient you kill them. Your build would probably rip through tanks and squishies alike but it wouldn't kill squishies as fast as a glass cannon build. Therefore, it's all up to you. You could definitely do well with that build but you'd have a different playstyle than glass cannon Katarina (i.e. you should probably focus on poking more in teamfights seeing as Liandry's is DOT which is why not many people build it).
