I do not have the exact command, and urge you or anyone else to post it, but you should be able to flash this entirely on using esptool.py.

This is the command we used to flash to nodemcu on macos catalina using the .bin files from this repo.

our prerequisites:

1. Install the appropriate driver for nodemcu for usb to uart
2. Install esptool.py via homebrew

sudo esptool.py --port /dev/tty.SLAB_USBtoUART write_flash 0x00000 image.elf-0x00000.bin 0x40000 image.elf-0x40000.bin

We are able to attach to esp via wifi but going to 192.168.4.1 only returns this error.

File not found.

Even though web interface isn't working we confirmed that our tv received the analog signal.

You do need to also flash the web file. You may need to do that via the network. I think it's
make netweb
