I blew away an old image for my raz pi and I can’t remember now but I could have sworn it was a regular Raspberry Pi [Jessie] image and I did not use docker nor did I install in a virtual python environment. Am I crazy? I can’t find instructions any more for how to just install home assistant directly on a Raspberry Pi
You should probably use a venv, even if you didn’t before. I’ve been using a venv since I started over a year ago. Works fine for me.

I don’t know why I have such a mental roadblock about that. I guess it seems like just another layer, a layer I don’t think I need.
Wait, so I have to use “Lite” OS? Does that mean I can no longer have HDMI output on the same pi?
No, google the differences. AFIK you can install anything the pi can use from Debian/Buster repo with lite version installed, you will need an internet connection.
For straight install you could follow instructions here: [https://github.com/home-assistant/home-assistant]
My advice if on a Pi, do the venv install as recommended above, due to the root user permissions issues, too much access to system for user Pi.
If starting over I also strongly recommend setting up the system on usb stick or ssd if your pi supports booting that way, helps avoid SD card issues in my experience. Just my 2 cents, YMMV.

If you want to run it on straight python, you need to be using a python virtual environment.
I recommend Docker instead though.
