ZZ'rot

Can i ask a very serious question about ZZ'Rot? why is it that they don't give gold when you kill the void-lings? viodlings do. it just seems to me to make it balanced i should be able to farm those minions just like anything else. with bandit on if one dies it gives 1 gold when a minnion kills it but if you last hit it yourself you get nothing. im kind of curious why that is. in early game if a jungle does something stupid and gives the enemy top a kill before lvl 6 and hes rushing zz'rot. there is no defense unless you have excellent wave clear. now you are pushed constantly and the twr has no chance of surviving. please explain why you cant farm the minnions. is it because its there for too long and if i do kill him and push wave i can farm the minnions off it for free? cause that sounds like a fair trade to me make use of it or have it backfire. sounds like a VERY fair trade to me.
