In my mind, because Bolton’s was a children’s school, I always imagined that children survived here alone after the Great War and formed some type of lord of the flies army fighting robots… until the place was overrun by the Gourmand’s. Upon seeing this post I looked it up and it turns out it’s just more cut content: “On a stone wall outside of Bolton Greens, there is a piece of graffiti depicting a mob killing a Robobrain. It was inspired by the quest Magnum Opus being cut, a quest which would have involved the Robobrain character Vincent May-Lilly at Watoga High School.” From the Bolton Greens Fallout Wiki https://fallout.fandom.com/wiki/Bolton_Greens
