It doesn’t really function as its own state since it has no separate courts (it owns and partially runs the Old Bailey, but that’s for all of England, not just the City), no defense or foreign-policy capacity, and none of the other functions of a state. It’s a Liberty (an area with enhanced or different rights) rather than a state.
It’s the same for England, Wales, Scotland and Northern Ireland. Or for 50 states inside the US.
USA states have their own: police force, congress, judiciary, laws, taxes, constitutions, and so on. So I’m not sure what you mean by comparing the City of London to USA states - it isn’t really meeting your criteria aside from not having a standing military which is also true for some countries/states outside of the USA.
