Is it permissible to tear up photographs of "the cousin's daughter" and the family, while lying to her that they were lost, or must they be returned, knowing that she will not tear them up if asked to do so?

Photographic images should not be destroyed; rather, they should be returned to their owner, because the ruling on photography is not definitive, and some scholars have permitted it. What is required is to gently and kindly advise the owner of the images regarding the prohibition of possessing images or photography altogether, without denunciation, disparagement, or harshness, as the matter is subject to juristic interpretation.
