Why do I have to individually block each site trying to do this? Why isn't blocked by default? Is there an actual use to this that can't be allowlisted?

“Users can control these permissions under Settings > Privacy & Security > Permissions. The browser also implements Local Network Access (LNA) standards, categorizing requests into Public, Local, or Loopback.”

Specifically, navigate to ‘about:preferences#privacy’ and scroll to "Permissions" to manage "Local network devices" access, which is often needed for routers, printers, or local development servers.
