Clearly, that's not true. Note that some us were long out of school by the time Barbara Liskov first published the idea (in 1988 according to http://c2.com/cgi/wiki?LiskovSubstitutionPrinciple). Also, since it pertains to OO programming it was probably not taught widely until the mid-90s. That means a fair number of people will have never heard about it.

...and then there are those Python users who have no formal CS background at all. Python is used quite a bit by people who's main job is not programming.

I'm one of those, and whatever I know about CS, I owe it mostly to the Python community. I learned an awful lot just by hanging out on various Python mailing lists.

I don't think that's any better. At the very least, people can Google for "Liskov violation" to educate themselves. I'm not sure that the results of a Google search for "Subtitutability Error" will be any clearer.

Well, with a bit of luck Google will point to the Python documentation then...
