Note that an AI or civilization of many ASIs could harvest the overwhelming majority of all accessible and suitable material on the planet and yet keep all humans alive if they chose to. It’s not an expensive thing to do. Humans are really cheap and live skimming off the very surface of the earth. Most of our raw material shortages are self inflicted, we don’t recycle CO2 back to hydrocarbons and we don’t recycle our trash at an elemental level.
The reason they might kill all humans would be either from a moloch scenario or one where it was efficient to do so to remove humans as an obstacle.
