You need to redirect the STDERR output of foo to /dev/null so you don't see the errors.

foo 2>/dev/null || pwd

Note that the error message can be redirected because it comes from the command_not_found_handle hook which runs in place of the missing command, rather than from the shell that spawns the command.

Pedantically, the error message can be redirected merely because it's printed on stderr. It doesn't really matter which process produces it.

You can redirect the standard error of the first command

foo 2> /dev/null || pwd
