They do make special shielding for USB and other ports, but most manufacturers don’t use them because generally people aren’t going to stick foreign objects into their computer for internet points.
Often times, those “public chargers” you sometimes see in airports and such have that shielding installed on the ports (though you should never use public USB ports to charge your devices, for a dozen other reasons).

USB condom works for public chargers. It’s called a “usb data blocker” and goes for under $10
Don’t you need to manually approve data transmission through USB?
In an ideal situation, yes. Not all devices even do this and when they do, there is the whole concept of hacking.
