Replacement Device Back to KitKat

I recently received a replacement device for my Verizon LG G2. My previous phone was kept on KitKat and I would like to get the replacement phone back to KK. The phone is currently rooted and I have TWRP installed. I am running Extreme v1.1 VS98039A.

Is there a way to take this phone back to KitKat 4.4? Thank you in advance for any help you can provide. Have a blessed day!
