You can make your own LUT, as described in chapter 2.28 in my book.
-- Extract one frame from your video.
-- Insert a haldclut in a corner of the image, or use xstack to attach it to
the side.
-- Use the program of your choice to correct the colors in this image. When
done, save it lossless as 16-bit PNG.
-- Use FFmpeg to separate the haldclut from the image.
-- Apply the LUT to the whole video.

What if the video is interlaced, the extracted image will be interlaced!
I don't know. I did never work with interlaced videos in FFmpeg.
I think I got this now, in lamens terms, just start at Chapter 2.28 when
creating a modified CLUT, as you initially stated.
That's right. Just start with chapter 2.28 because it's easier.
