I invite others to take a stab at this. A fresh pair of eyes always helps. It’s cool that such a resource was found. Granted it’s more than a little weird that the Kilrathi would have a 26 letter alphabet, but whatever. We’ll just work with it.
However, my work is hampered by a few things:
First off, the camera angle is slanted slightly, making it tricky to determine a shadow from a shallow cut in the stone at.
Secondly, some of the letters aren’t exact matches, and other could be any of two or three characters. Still some of the letters/characters on the tome appear to be mirrored or inverted versions. And a few appear to not be on the list. I can only assume that if these is some sort of Alphabetic writing system, then it has many more than the 26 letters listed.
Now, the fact that some of them appear to be reoriented in different directions, similar to the characters seen in the movie, makes me wonder if there is some underlying element of the Kilrathi psyche at work here.
For real world example, if you take the symbol for “War” (it kind of look like a bird’s foot) and invert it, making it negative (while placing in a circle representing a continuous or endless existence) then you get the famous “Peace Symbol”. Symbology can be a fun, and at times eye-opening, excursion.
