Since CS is a FOSS project, am I legally allowed to sell the bots I make with CS? Specifically, selling the topic and control scripts to a company that wants to host the server on their machine and use a JS clientside script to communicate with the server on a webpage I make for them.

According to the license, yes. There is also nothing stopping the company you’re selling to from downloading the scripts themselves for free.

see thats why i dont understand why CS not more visible online….....ML is a horrible way to train an intelligent bot…...it basically understand pos like noun(entity) and verb(intent) but not really meaning…..you can make dumb bots…..even bots that just give buttons to click on…...but if you dont mind coding and enjoy thinking of interesting patterns, CS is the best one out there! But the group is really small for CS forum here…...i love the challenge of CS! only competitor CS is Watson Assistant and even that falls flat…..
