I know you're wanting to dig to the bottom of this, but this forum only helps so much -- after that, it's a necessity to speak to a local attorney, and in your case that's your next step.
I can't tell you what to do, but you should certainly not begin contacting anyone and telling them she's no longer a member when she legally is a a member.
Giving her notice of a capital call, which she won't pay, does not automatically remove her as a member. You'll have to take the appropriate legal process to do that. This usually is not possible without court intervention when there are only two members and neither holds a majority of the interests in the LLC. Thus, this is not a simple matter and really does require a local attorney's services. They can spend a lot more time with you and communicate with you much better than you can do online. It's more expensive, yes, but very valuable.
There's so much that I cannot properly convey or assist you with online because back and forth communication is too time consuming and the issues you have will require an attorney hitting the law books and spending some time ensuring there's no loop hole in the law that could bite you.
