Difficulty in bot games for newer players

First of all I am a Diamond V player. I have been trying to get my friend into league. My main problem is that the beginner bots with the keystones are doing a bit too much... I swear after patch 7.22 the bots have gotten smarter and stronger (stronger prob bc of the keystone... maybe smarter because they can actually kill me now). Basically, i was ccd by the bots for a solid like 4 seconds to death in multiple games. Lux snare into taric stun into ryze snares... or my fav the taric into leona stun while the renekton bot is hitting me. I have also been destroyed by the mf+taric bots at bot lane with my friend because they just kill him in the stun duration because he doesn't understand how minions really work yet. The stupid taric leona and nunu bot (screw the nunu bot) NEVER DIE. They are just too stupid tanky. Before anyone asks, yes I did win the game and I got a ton of kills etc, but the problem is the bots can actually kill me and I can't just 1v5 them like in the old system, which means my friend with the like 10 deaths because he is still learning isn't having a good time.

The intro bots are not even worth doing just because they come to lane super late. I know it is good that the bots are harder/smarter, but I think that is best saved for the intermediate bots not the beginner bots. My friend literally isn't learning anything he just runs up and dies. (also on a side note the pre-set champions for new players should return instead of giving out the free rotation because my friend was learning just fine with lux until she was taken away)

tl;dr- THE BOTS FUCKING HURT AND SOME OF THEM DON'T DIE Also i'm not dying to the bots because I am "bad". It happened the first couple of games because I didn't expect the nunu bot to chase me into the jungle and all the way half way across the map or get chain ccd perfectly. Before the patch I could literally just run up auto a bot and it would die and now I either get stun locked to death or a bot like the nunu bot literally won't die.........

E: stating rank was just to say that the they chain cc better than most ppl at my elo too and it really isn't expected. E2: No I didn't lose a bot game, but my friend would have lost some with the other new players if I wasn't in that game. It wasn't hard for me it was hard for him and it was overly annoying for me. Even with several kills and a couple items on riven the stupid nunu bot took forever to kill. Also, sorry about the formatting it is 2:12 in the morning and I cannot think.
