Depends on your shell; a lot of shells with command line editing will
not literally echo the ^G as you type it but embed a visible ^G in the
command line (echoing ^ and G, not the BEL character), and ^G may also
_be_ a control code for the command line editor. As it is in the zsh I'm
using.

So, yes, on a traditional cooked mode command line typing a ^G will work
because it will be echoed directly as it is typed, but it's not always
the case (and, indeed, not the case where I'm typing:-)
