Return whatever you'd like to send, and it will be sent back to the caller. You may also want to set an appropriate content type in RestContext.response.headers to make sure the response is interpreted correctly. Example code follows.

if(accountList.isEmpty()) {
    return JSON.serialize(
        new Map<String, Object> { 
            'success' => false, 
            'message' => 'No accounts were received, so no accounts were created.'
        }
    );
}

Alternatively, you can set a response in RestContext.response.responseBody if you'd like, which would allow you to change your method to a void return type. It's up to you which design you prefer. Finally, if it's truly an error, you may also choose to set RestContext.response.statusCode to a non-200 value (400 would be a good choice, meaning "Bad Request"), but this will depend on your caller's needs.
