As every other player, the bots would -in theory- see the blood splatter on their screen. So even if they don't see you poppin up on the minimap, they knew from which direction you're shooting them, when using a silenced weapon.
Now on a lower difficulty-setting, the bots will probably ignore the blood-splatter for the most part, just like most players do.
However, on the highest difficulty-setting, I expect them to use this information to use it against a player. Obviously they should not turn around and instantly start shooting at you, but after they have "scanned" the general area they should be able to figure out where you are; again, just like real skilled players.

I don't know if you ever played Black ops, but in combat training on the hardest difficulty it is halfway impossible to do anything. You can be hiding behind a wall and pop up for a second and be head shotted. On the kill cam the AI was turned the opposite direction and instantly locked onto you. I would just hope it is not like that.
