Was I the catalyst for this games loss?

I was Lee Sin last pick because I didn't have any other jungle champions, and already I knew it was a bad idea because their picks pretty much effectively shut me down, but Zed went 0/6 in at least the first 15 minutes, and I don't blame him, Vlad vs Zed is a difficult matchup, but when I started building Hexdrinker my Malphite chimed in and said "nice build lee :)" like I was building wrong, but they have an AP heavy team, and at this point everyone who was AP already had a fairly high kd... the malphite again continued through the game overall being generally negative towards everyone for no reason.

This is just to showcase some stuff, people use League of Legends games to learn most of the time, at least, it's what i do, so why do I need to have people like these in my game, who say what I am learning is wrong? Now, if I had somebody who was Diamond and up tell me that the build path I chose is wrong, that would make me change my build the next game, unless they say it in a negative way like "what the f### are you building you mongoloid such and such" then what am I going to learn from that? When you yell at your dog, it doesn't fucking learn anything, you're just screaming at somebody who can't understand human speech, it's the same thing, unless you say shit nicely, nobodies gonna listen to you. It just will not happen.

But I want to know if this game is solely my fault for picking lee sin last pick into pretty much ungankable lanes unless they're really bad

Anyway, if somebody who isn't bad at the game like me, or somebody who actually has the credentials to tell me what to build and what to do, if they can tell me what I can do better, I'm willing to listen, and to learn.
