The term Bots in League of Legends refers to a computer controlled opponent (AI - Artificial Intelligence) available in custom games and Co-op vs. AI matches. Bots can have either "intro", "beginner" or "intermediate" AI. Intro bots aren't available to use in custom games and are exclusive to Co-op vs. AI, as well as some bot champions can't be chosen in custom games while being available in co-op vs. AI.
On January 24, 2012, it was announced that the bot system would be expanded with more bots, better intelligence and availability on the Crystal Scar. On February 1, 2012, the system was released.[1]
On April 15, 2014, an update to the bot AI was released, primarily improving threat evaluation and the ability to dodge skillshots, as well as updating the item builds used.[2]
In V6.3 and V6.4 Riot added more bots to the bot roster[3] now available only in co-op vs AI, which were temporarily available to choose in custom games on the PBE server. It has never been implemented in the live servers.

Items
As of V11.3 bots build items based off of the recommended items tab, which is a system that updates as players build differently. Historically bots had a set build path and would buy the same items every game.
In this table you can see what items the bots buy first. Bots always buy the same items.
