What you’re describing sounds like an AutoML tool, of which dozens already exist. Various companies offer a subscription service to access an API for their tool, and charge by usage/time. Maybe I’m missing something but I don’t see why companies would lease IP rather than just use a service. Like AutoML software is typically used by companies who have very few ML experts on their team so the API makes it easy for engineers to integrate ML into their products, while companies with many ML experts usually just build their own AutoML tools
