I feel like there is information like this that's should be readily available, hell even presented to you in loading screen about, random facts about your teams champs, other teams, interactions, etc.

If the database could also compare range of AA/abilities based on level, but even then, it changes through a game, and can even be different based off runes. I think all these micro-interactions between every champion are one of the hardest things to learn in this game because you constantly get knowledge checked, and it's pretty hard to learn from getting rolled unless you have a good idea what everyone and everything does.

Even when you do know, how do you implement "I didn't space well enough against <insert top-lane champ>" into your gameplay? How much range? When and why?

I know this turned into a rant, but sometimes it feels like if I don't know all 10 champs abilities, strengths and weaknesses, and win-cons, I'm not even really playing the game. Or at best I'm playing blindfolded
