No idea about Glen Ellyn, but I can tell you for sure that you will be able to find likeminded homeschooling families in the Chicago area. Even those who are A-Ok with 'queer' My eldest dd lives there with her kids (south side) and tho she is not a homeschooler she is connected with various progressive and 'queer, or queer-friendly' people all over the place. I can find out if she is willing to communicate with you or at least give links to regional elists that will help you get connected. PM me for details.
I don't know about the burbs, but there are a couple of homeschooling groups on the north side of Chicago that I would suggest. If you are interested in living in the city, let me know and I'll pm you more details.
