Best implementation is to likely just add a callback to the reCaptcha and add it as a data attribute to the container div. A custom jQuery Validate rule would then check the data attribute for a response and decide what to do from there. This avoids using getResponse and avoids having to possibly reset the captcha once the verify token has been used.

A text input marked required that is filled with a value based off the callback response could also work. Then jQuery Validate would be able to simply automatically handle it with no additional custom rules. A hidden input won't work as by default cbValidate jQuery Validate implementation ignores hidden input so it needs to be text with display none style.
