3 routers / 1 switch. I have questions
I have 3 routers. #1 router: Hooked to the cable modem, IP 192.168.1.1. Has some devices hooked to it like my google phone & My Verizon extender, Amazon Firestick. Just my devices that I don't car...

The answer is simple. The power outage caused a device on your network that was configured to not serve DHCP to lose it's configuration and revert back to factory. The harder problem is figuring out who lost their config. You can start looking through the logs on the various devices. You will most likely find the answer there. But there's no fun in looking through logs.
If you're just mildly curious you could try a test. Do an ipconfig/release and renew or reboot something that erroneously has a 1.1 address and see if it still gets a 1.1 address. If the 1.1 address persists then unplug the Cat7 cable between router #1 and router #2. now do another ipconfig release/renew and see if you still get a 1.1 keep removing items that can possibly feed DCHP, don't forget the garage access point (my suspect by the way) until you finally disconnect the one feeding the erroneous IP's.
Edit to add... If rebooting the affected devices restores them to the 2.1 subnet, then yeah your only answer is in going through the logs of the various routers and see who assigned the IP.
