What do I do when I have this kind of teammate?

I just had a game where I called jungle, the teammate, uhh, no naming and shaming so let's just call him Fizzer (not actually his/her summoner name), basically butt in with jungle Jax whereas I was jungle Kayn. We started off the game and my initial plan was to place a ward in the river botside first to watch for invades and then go to my bird camp since I can solo. I was initially hoping Fizzer would get a leash for blue or something but he instead he followed me to the bird camp and tried to wait for me to lower everything for him to last hit. He kept following me around and kept last hitting camps with smite or Empowered Leap Strike resulting in me being Lv. 1 for like the first 4 minutes. No matter where I'd go, he'd follow and if I'd gank he'd be busy avoiding fights just farming and taking as many camps as possible.

Despite him having more gold than me in the end of the game he still had the same dreadful score of 2/9/2.

I have a feeling some of you will just tell me to play Draft but I'm not too sure my champion pool is ready for that. LoL's BE/champion gain system feels super slow compared to other MOBAs I've played so it'd probably still be a while until I can Draft Pick.
