What would you do with a bridesmaid who can’t hold her alcohol?

Hi all! Hope everyone is having a wonderful weekend! Apologies in advance for the long post.

I have a conundrum that I want peoples advice on. I have a bridesmaid (BM) who I’ve been friends with since we were children. BM has always struggled with drinking; not that she’s an alcoholic or anything like that, but when she does drink while going out (I.e. not a dinner or something) she‘s bad at cutting herself off and is more likely to blackout. When she blacks out, she becomes aggressive, emotional and needs someone to take care of her.
We used to spend every New Years Eve together and after multiple years of taking care of her, I moved away from that. For a few years we didn’t do anything that involved going out, but for my birthday this past year, we traveled out of town together, went to clubs and bars every night, and she was fine and held her alcohol very well.
A few weeks ago, we hosted an “Engagement Party” (really an excuse to get all our friends together at a bar) that she came into town for (she lives a plane ride away). Everything was fine for the party but the party turned into an after party where, I’m not sure what happened, but at some point she went into her blackout state and it was possibly the worst I’ve seen her.
To name a few events that happened when she blacked out, she:1) Bit one of my FH’s groomsmen, tried to make out with him, and when he said no, punched him 2) Stole a girls purse. I found BM in the bathroom with it and when I asked where she got it from, she said she was holding it for a friend. The “friend” was frantically looking for it. 3) Left her blazer in the bathroom and then tried to convince me someone stole it when I found it there 4) Cried when some of my friends left. I told her that they were adults, they were allowed to leave but if they wanted to come back they could text us. Then got upset with me for telling her that5) Jump-danced in the middle of a packed dance floor swinging a giant purse around, hitting people pretty hard (I got some bruises from her “dancing”)
I’ve started hearing additional stories from some of my other friends who were there, things like her stealing people’s drinks, becoming physical when it was unsolicited, etc.
I’m not confrontational at all, and typically I’d just not say anything about it, but A) I think she owes some people apologies for her behavior and B) I’m now REALLY nervous about her at my bachelorette. I plan to have it in Vegas or somewhere with a party atmosphere and I’m very nervous me or one of my other bridesmaids is going to have to spend the trip babysitting her. I’m also concerned about her at my wedding, although her parents will be in attendance so hopefully they can rein her in.
So I guess my question is, have you had any similar issues? Is there a good way to approach this? I want to be honest and tell her my fears, but I also value our friendship and don’t want her to feel like she needs to tip toe around me for my engagement. I’ve heard advice from “come up with a plan with her to address her drinking” to “don’t invite her to the bachelorette” all the way to “ask her to step down from being a bridesmaid”. What would you do in a situation like this?
Thank you so much in advance for your advice!
