Legal liability is paper thin excuse. Very few companies have been sued for sending an email after saying "we didnt hire you coz you look like you might get pregnant" and playing that off as a "risk" doesnt really add up. You protect against liability by telling hiring managers not to break the law before, during OR after the interview - coz the company is exposed in all three. Even so many companies are deficient in this regard. Simple laziness and wanting minimize reputational risk from feedback on the feedback seems a more plausible as a reason why.
