I downloaded client for TFT and just started playing summoners Rift about last month. Tutorial did not help me much at all either. As a result I just looked at some articles and youtube videos to get a better understanding of things like the Drakes and monsters in the jungle, items, runes, lanes and roles and all the other stuff that really confused me at first. All I did was google "League of Legends for beginners" and clicked some stuff that popped up.
After I felt like I watched/read enough I played a ton of AI vs Player games I probably have like 150+ under my belt not sure. You probably wont have to play that many though. It took me a minute before I was comfortable enough to do
Player vs Player but eventually I did.
I'm still pretty bad but getting better after every single game, each time you die ask yourself what you could have done better in the situation or the time leading up to that situation. I've found that in forums and youtube comments this community is pretty friendly with newer players but in game not so much so just put a helmet on and be prepared for that lol. I also feel like I get matched up against and with players way above my skill level but I love a challenge so it's fine with the problem is they tend to be pretty toxic. People in the AI games I played were usually really cool and helpful though so when you are playing ask all kind of questions I'm sure they will help.
So yeah just google a guide, check it out, and than start playing. There is other stuff that the guides may not teach you that you will just have to seek out specifically. Personally I had trouble with getting minion kills and gold at first (something not really explained in depth in the beginner guides I viewed) I would always have like 50 or so minion kills and about 6k gold all the time while my teammates had 100+ minion kills and 10k + gold. So I googled best ways to do that specifically and found some videos on it.
