Only for transmitting, but yes. It uses only on-board hardware for generating signal, think it's using the same part that allows to output composite video via headphone jack if I remember correctly. RTL-SDR can be used for simultaneous TX and RX, GPIO for sending and RTL for receiving

It just needs a single GPIO pin with correct frequency range, see RPITX project (transmitting radio using only Raspberry's integrated hardware, anywhere 5KHz-1500MHz). Airgapped is not enough for this, lock it in a faraday cage.

Another possible attack vector is corrupting human mind via user interface, either visual & auditory or a brain-computer-interface (in near future). First option is something I'm sure was researched by US military/government given what they were into in the last decades, looking at some declassified docs. Just waiting to be perfected by an AI.
