No you don't.
You can have the public IPs on everything in your LAN... and still it would be completely inaccessible to the outside world. Because you know, firewalls exists.

Bullshit. BGP doesn't 'expose' your internal routing configuration and there is absolutely no other way for someone to see how exactly the things in your network. OSPF could be used for it, but it requires: 1) being right next to your router 2) be configured to send on the external interface.
Exposing your LAN configuration for the whole world to see is insanity. (Yes, we sometimes do this, but only because we still don't have sane VPN solutions here in the year 2022.)
