In my state a person who is not charged in a self defense shooting is immune to civil suits.
This is a complicated issue. The short answer is that there are no states where a person is actually immune to civil suits. The law may provide, in some states that a suit must be dismissed under certain circumstances and may provide that the defendant is entitled to recover expenses incurred. But you can still be sued and will still have to hire a civil lawyer and go to court. If you can show that your case falls under the immunity protection, the suit would then be dismissed.

Note that the law provides that:
"A court shall award reasonable attorney's fees, costs, and trial-related expenses to a person in defense of a civil action brought by another person if the court finds that the person is immune from civil action as provided in this section." Clearly that wouldn't make sense if the person didn't have to defend against the civil action in court.
Your advice, however, is good. The person needs to keep quiet. If they feel like they must release a statement, they will need to get a criminal lawyer, experienced in such cases, to do it for them.
Also, if needed seek counseling to overcome any emotional trauma if needed.
Yup, this kind of situation can really damage some folks. If she's having trouble, getting help sooner than later is a good thing.
