Disney is denying it as of today:https://www.theguardian.com/film/2017/jan/13/carrie-fisher-disney-negotiating-for-digital-rights-star-wars
I seriously doubt anyone is bothering her family over something like this now. IX starts filming a year from now so they have plenty of time to work out what to do with Leia. If that involves some kind of digital anything, then there is enormous amounts of time to work that out. There is no need for them to even go there now without any understanding of what they would be using or if they would be using it, especially with a script that is likely nowhere near complete.
As for what I'd like to see done with Leia personally, I really don't know. There are no good options. One is to recast her, which I think is a non-starter. Another is the digital route, which depending on how necessary Leia is to the resolution - I'd think very - may be the only option. The last would be to simply kill her offscreen (cheap and unfulfilling) or let her disappear out of the narrative (on a mission to such and such) also cheap and unfulfilling. It's going to be a tough decision for them to make.
