The first champion I played was Riven because she had no skill shots or targeted abilities. I also hated playing ranged champs for the longest time. For about my first 10 levels of play I thought that bot lane was easier because it was a duo lane. I didn't understand certain champions were built for certain roles that were played in certain lanes, so I would play riven bot (at least she can be a melee adc?)
I didn't know that ability power = magic damage, so I thought that building AP items would make any champs abilities do more damage, so I built AP riven because I thought it would make her Q and W more powerful. Needless to say I got my first actual kill at level 8, and that was entirely a ks.
After level 10 I played Akali, but I was really bad at hitting my combo, so I would just mash Q and R without knowing what it was they did, just knowing they caused damage. Somehow I got a few kills with her that way.
