What's the best way to get into league?

So... like everyone else I want to start playing league after seeing arcane and Ive had a bunch of fun in the games ive played. However, I'm starting to realize how techincal this game is and its all very overwhelming for a beginner with things like what items to buy, characters to use, and what the enemy characters do. While I also would appreciate if some of yall could answer my questions, I mainly just came here to ask if yall think the best way to learn league is through content and tutorials or just playing the game a bunch and learning from practical experience? (Also please don't say the "Just don't play league " bs, some of the playerbase for this game can be so annoying with how unwelcoming they are.)
