I bought an Essential during one of Amazon's sales and I have finally produced a working, official TWRP for the device. I tested it on Essential's 9.0 official firmware with August security patches. Touch works and TWRP is able to decrypt your data even if you have a PIN / pattern / password set. MTP may or may not work, depending on what kernel you are using. The screen is still not using the right-most edge of the screen, but I've implemented a few dirty hacks that I will clean up later to make TWRP fit the screen better. It is NOT recommended to use custom themes at this time on this device due to the screen weirdness.
Since the Essential is an AB device that does not support fastboot boot, you will have to flash the initial TWRP image to the boot partition. You can either switch slots following the instructions on our website or download the latest factory image or make sure you have a recent copy of your current ROM so you can reflash the boot image. Take your pick. Especially for your first install, I recommend doing the install when you are close to computer so you can fix anything that may go wrong.
