Girl's Behavior

AITA for wanting to ask a girl to leave the group chat?

Yes I know this isn’t Reddit but hear me out! So before any of you say yes you are here is a bit about the situation! This girl lets call her Jamie (24 years old) she sends the most random messages to the group chat and I have even had multiple people from the group chat privately message me saying she's getting a bit annoying about it and I have to agree. Like I previously have mentioned she asks us the most random questions about what she should get at a restaurant or what she should wear to an event she's going to and sometimes even shows us a bloody scrape that she has on her leg. Which is absolutely disgusting by the way. I have messaged her privately asking if she could dial down the random messages but she still hasn't! Like yesterday she asked the group chat to wake her up at 7:30 am which I told her to just set an alarm! Most of the people in the group chat just ignores her which I do as well but she messages the group chat nonstop so it's hard to just ignore her! I would ask her to leave or even kick her out but I'm not the creator of the group chat and only the creator of the chat can kick her out (and I also don’t wanna be rude even though I have definitely thought it) but the creator left the group chat months ago so that's not an option! So AITA for wanting to ask her to leave the group chat?
