Does DFACS consider a 17 year old an adult in Georgia?

No, you're still a child until 18; however, Georgia allows you to go to jail at 17, so that creates a bit of a loophole. Parents cannot kick out a child until age 18, but the child can leave on his/her own at 17 and cannot be forced to return. Be aware that you cannot sign any Contracts or Leases until age 18.
