So Chi-Chi’s initial response here was the first thought I had while reading this question. Palling around with a former villain isn’t exactly out of character for Gohan, and that’s probably affected Chi-Chi’s perspective to some degree. But then I decided it’d be fun to spice things up by having Gohan not be the only member of the family Zangya likes to play with! I don’t know if there’s much Zangya/Chi-Chi content out there, but I thought it’d be a fun twist on things. I opted to go with Chi-Chi’s design from the Bojack film, since that seemed most appropriate.
