League AIs gaining sentience?!?!

So i'm a little afraid right now... because i think the league of legends AIs have evolved sentience... and are adapting. I was just in a custom game as bard, 50ish minute long game; it was normal for most of it. But then about halfway through... i started getting pings - not like lag, but like the ping system. I never saw who used any of them, but they kept popping up near each of the AIs. Near the end i decided to start collecting as many meeps as I could, but realized that my two AI's (Soraka and Malphite) were going deep in the enemy base. Malphite died pretty fast, and he looked like he had a standard build, but the Soraka bot's build was NOT the standard beginner bot Soraka build. I watched it playing for the last 20ish seconds - it was FRIGHTENINGLY intelligent. She was pushing up the inhibs and positioning herself perfectly behind minions to avoid getting picked off, all while harassing with her silence and starfall. The most eerie thing happened right before the victory screen - she was attacking the nexus, and the enemy Miss Fortune AI came to try and stop her - Soraka immediately turned around, used both her skills and attempted to kill her. (All AIs in the game were beginner; there were 5 champions on the enemy team, and including myself 3 on ours. I was the only player in the game.)

EDIT: Here is the match history, though it doesn't really show anything significant. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1777742386/47810311?tab=overview
