I think you are confused.This is my point, it agrees with common sense ideas about what God is but not with a single part of the definition you gave - he isn't worshipped, he doesn't control aspects of the world or our life and certainly isn't the personification of a force.
Your confusion I believe stems from you using two different interpretations of Brahman, one in which he is a 'creator' of everything and all that... on the website you linked, you don't think that's a form of worship?This is the problem, he isn't worshipped and doesn't do anything. He is thought of as "ultimate truth", "the ground of all being" and the source of consciousness that we are all a part of but not an active thing that controls or affects things.
The other which you are trying to say is what ISN'T a god... well it really ISN'T a god, even to the Hindu, it's just the 'substrate of EVERYTHING'.
This isn't worshipped but there are other gods which ARE worshipped. Mainly Vishnu, Brahma, Shiva, or Shakti. There are others depending on the Hinduism you speak of (some don't even involve god at all and are all philosophical.) These four gods are what comprise the supreme substrate. They are all worshipped.
I still am failing to understand how the 'universal substrate' which all of us come from is not a personification of a force in the universe... It's just EVERYTHING all in one... still being personified you have yet to show how it isn't.
