This isn't a perfect match but I haven't found any other isekai or kingdom building stories tagged with "robot/s" or "artificial intelligence".
This may be Mynoghra the Apocalypse: World Conquest by Civilization of Ruin, aka Isekai Mokushiroku Mynoghra: Hametsu no Bunmei de Hajimeru Sekai Seifuku
I reincarnated as an evil god. Ira Takuto succumbed to illness at a young age and ended up reincarnating in a world that resembled the strategy simulation game, "Eternal Nations", of which he loved playing when alive. What appeared in front of him was Atou, a girl belonging to the evil civilization that he used to play as, "Mynoghra". The two of them decided to create a new country in this world once again.
The main character dies and is reborn within a game he used to play, alongside his attendant Atou. Atou has silver/blueish hair, not blonde, but in a black&white manga they both appear light. Atou is a character from the game and is aware of the world being that of a game. She is not a robot, and in universe she appears to be the same as any other humanoid, but I believe "self-aware character from a game" is reasonably close to her being considered an AI.
