IANAL, but I have a theory on Lori’s defense. It’s all IMO. Hopefully it’s okay to post.
This assumes that LE has enough electronic and/or physical evidence to male pinning the crimes on Alex a bad defense.
I’m sorry if this has been discussed at length and I’ve missed it, but the following University of Idaho Law Review link clarifies Idaho’s lack of an insanity defense, and that mental condition may be considered for establishing mens rea (intent).

If I’m understanding it correctly, it sounds like Lori’s mental condition can come into it.
I think that the example on p. 18 of the PDF (p. 592 of the document) indicates that her defense could argue that she lacked mens rea to murder her children because she truly believed that she was killing zombies—not humans—so she lacked the intent necessary to commit first degree murder. IMO, they’ll likely argue this hoping to get it down to second degree murder or manslaughter. (Chad’s defense could technically go the same route.)
This sounds similar to diminished capacity to me, but again IANAL.
Diminished capacity and mens rea (vs. not guilty by reason of insanity) are discussed more generally at this Cornell link:
