You must have intention to be able to create, things without intention are not creative but a mere tool, your intention may be something else, as I stated earlier you may create a weapon in order to hunt something.You can not "randomly select" a goal, the goal is the thing the nural network is adjusted into.To be cretive you must be able to create new goals in order to solve unknown new tasks.You are right that agency is required for general AI, we don't have it. Maybe we will never have it in our machines and frankly AI-less future looks somewhat more promising to me as an individual than its opposite.
Intention doesn't influence creativity, because intention can be set by the designer, or randomly selected from a noise seed.
