A tip for new players to avoid raging smurfs
Play bots games till around level 10. I've been seeing a lot of posts about how bad the new players experience is, and it always confused me because I never had that issue (I started towards the beginning of S4.) But if you play against bots, first of all, there is less toxicity. Not getting raged at constantly really helps for the learning experience. Second, if you are up against bots, you are probably going to be winning a lot, if not all of your games. This gives you a confidence boost as well when you are playing, which in turn makes you better. Now that doesn't mean you can't play pvp at all, ( I played pvp with my friends when they were online) but playing lots of bots games is what helped me in the LoL experience.
