There are currently roughly 5000 satellites in orbit (per wikipedia). I don't have good stats on those 5000 satellites but I believe they are on average substantially bigger than the starlink satellites.
Either way, a few thousand things spread out over the surface area of the earth is practically nothing.

and the surface of a sphere at the altitude they're orbiting at is even larger. and the satellites are all spread across a variety of altitudes, relative to their size.
Satellites already have a nontrivial effort put into keeping their orbits from colliding with each other. Increasing that number by 50% is not going to be easy.
First, I don't think space is either American or Non-American land :)
Second, I imagine outer space treaty covers this in much similar way that treaties governing international waters do.
Third, to a certain degree "satellite trash" is in the eye of beholder - I don't think there's any more or less legality in this, than in ISS, TV and comms satellites, GPS, etc all flying all around the world.
No one wants to get into a real estate battle in space. At least not yet. Maybe some day it will make sense to some nation but right now fighting that battle is a negative sum game.
Not that these launches are launching trash, or launching very much in the grand scheme of things either.
