Luden's Echo's tooltip is as clear as it's in-game visual effect (Not clear)
Luden's Echo: Passive UNIQUE: Gains charges upon moving or casting. At 100 charges, the next instance of ability damage you deal will expend all charges to deal 100 (+ 15% AP) bonus magic damage to the first enemy hit and summon up to 3 lesser bolts that target nearby enemies, prioritizing enemies damaged by the ability and champions over minions.
Suddenly, you try it on Ezreal for maximum Q proc damages. Q is an ability. I'm pretty sure. Didn't proc'd.

Solution: Either it is a bug that should be fixed or it should say magic damage from an ability.
