There is literally no way around this. Every game has this problem. The thing about league is that new players generally don't play a large amount of games due to time constraints or frustration from an absence of a modern NPX infrastructure. They play 3 games where they get crushed by smurfs and I agree, it isn't fun. But there is nothing Riot can do about this, because a lot of smurfs deliberately try to game the system to seem like new players.
The only thing they can do is build a better infrastructure that makes it so smurfs are not required to play large amounts of games in low mmr. My mmr in normal pre-30s gets up to the equivalent of diamond 2 in about 30 normals. But if a player even knows what websites to go to for builds he will crush any other new player that doesn't, as a result, games are very one sided, and they didn't use to be when I started playing (season 1) because everyone was bad. Game has evolved so much that if you go into it like a singleplayer game and take in no information beforehand, you will get stomped more than a shantytown does by a nuclear weapon.
Its not like Riot can go the mmo route and disable pvp in new player zones, so its not that easy. You SHOULDN'T have to suffer through it, but you do, everyone does. In every competitive/pvp-multiplayer game. Its just the nature of the system.
My advice, just completely ignore normals until lvl 20-25, just play as many champions as possible and you'll get there really fast. Normals will be less fun than bots until you understand the reasoning behind the lanes and hard-meta. So just focus on getting more comfortable with csing, the controls, and learning everything you can about all the champions and items. When you hit 30, you'll crush people that way, and can get on your way to a fun experience. Pre-30 is an outdated system that does not age well against an evolving game, sorry.
If you REALLY wanted toplay normals, you could just deliberately lose about 10-15 in a row so badly and watch the tryhard smurfs flame you for no reason, and laugh. Those players are so bad anyway that they are just taking frustration out, trust me. Watch and laugh, then have fun at your level. Don't take it to heart when you get crushed by someone who's played literally 2000-3000+ more games, watched streams for hundreds of hours, and sometimes gotten coaching, and they go 15 0 on you, thats expected, theres nothin you can even learn from that, so just take it as a fun little excersise in "how bad can I lose? How dominate COULD I be?"
If you really want to get into this game, it is great, but you need to understand 1 thing: 1 game is nothing, 100 games are nothing, 1000 games can be a little bit. Even losing a promo in ranked means absolutely nothing, because if you go to op.gg and search your name, do "check mmr" it will go up/down 10 points if you win or lose that promo, and same if you go from 20lp to 60lp, Riot's ranked system is meaningless, and MMR is the only thing that matters. As long as you are improving, and having fun learning, you will raise mmr, and it isn't very time consuming. Ignore what your team says during game, they are mindless. Only focus on yourself, and your fuckups, and you will have an incredible time playing this game. If you don't, and ignore this advice, you will become a very frustrated player, stuck at a certain level, blaming teammates, creating negative experiences, and eventually quitting, and having no awesome enjoyment to show for it.
Give respect to others, and your enemies, respect their skills, and they will respect you, and your improvement and play will reflect that.
Good luck, don't worry about your KDA. It's only use is to show how bad someone's mindset is when they care so much about it.
