No, penetration is for when you largely do a single damage type, and need to counter Armor/MR. Hybrid Ezreal is already doing both physical and magical damage, it's almost impossible for most champions to counter hybrid's damage without hurting their own DPS. That is the basically the point of hybrid builds in the first place. Why do you think that Akali players don't build any penetration items? Spoilers: it's because Akali does a lot of physical damage even when she builds AP, so countering with straight MR isn't a 100% effective response.
