But here you specify all "statements about the world". In that case I can say outright that in no meaningful sense does there "exist" something not in the world which cannot interact with the world. By the generalized p-zombie principle: if it cannot interact with us, then it is not causally involved with your reason for speaking about it.
I don't find the generalized p-zombie principle particularly convincing, in part because it's not clear what "interact" means.
It does not have some Platonic independent "existence" because existence is a predicate of things in the physical world; it makes as much sense for a pure circle to exist as to not exist.
I think you're using the word "exists" to mean something different from what I mean by it. This may be one source of confusion.
it's not clear what "interact" means
It means 'causally influence in at least one direction'. Two systems are said to interact if knowing something about one of them gives you information about the other.

I know two meanings of the word 'exist'. First, predicate about states of the physical world (and by extension of other counterfactual or hypothetical worlds that may be discussed). There exists the chair...
