Not ignoring it per se. They recognize the LLC as tax transparent and as a result they apply personal taxes to you.
Different story is if the LLC is a real corp, and as a result not tax transparent.
UAE government can lack in a bunch of things, but they are not retarded. They understand why most people live there, and based on that they create rules to keep all parties happy; all parties being residents and
OECD.
Tons of countries consider US LLCs as tax transparent too,
Spain for example does and its nowhere near a low tax jurisdiction.
EDIT to add: A US LLC is basically just you with a front name. It's not a real corporation unless you apply for S/C corp status. It only serves the purpose of reducing liability, but for tax purposes it's just you.
