TROLLS OR BOTS?

Me and my friend that's fairly new to league wanted to play some normals. We get into champion select, I call adc, he calls jungle. But then there is some guy named Botttttttttt( I don't know how many t's) and some other guy called 123(something). Both of them lock in, one is Nunu, and the other locks in Ezreal. Nunu takes Clarity and Clairvoyance. Ezreal just takes heal and flash. None of them say a word, and now I'm angry because I had to dodge. Were they actually bots or just a couple of salty assholes?
