YES it is fanon, the manga states she is the "Progenitor of chakra". Progenitor does not mean the same thing as creator. The dictionary definition is:

"a person or thing from which a person, animal, or plant is descended or originates; an ancestor or parent."

The definition of creation is:

"the action or process of bringing something into existence."

Though she is the origin of chakra that doesn't mean she created. If Hypothetically speaking I swallowed all the water in the universe then a few centuries later it was redistributed, I would be the point or object of origin but I still wouldn't be the creator of water.

In the same way the Shinju was present before Kaguya ate its fruit i.e. its very much possible chakra already existed before kaguya and it was simply all consolidated in the Shinju. WE DONT KNOW. For all we know the Shinju could have been very much capable of combining physical and spiritual energy.

This means she may have or may NOT have create it.

So as others have said, what you've said is not fact but just a theory.
