I am not sure I understand what is the problem and what complexities
you are talking about.

I do know that "let's just quadruple number of
dimensional CSS properties" *will* increase complexity of the
whole system...

Ok, back to :ltr/:ttb.

p:ltr and p:ttb are just advices like:
this <p> element is now in LTR or TTB environment.
Not less not more.

If needed you can ignore such advices and use something like:

html[enforced-dir="ttb"] * { direction: ttb; block-flow: horizontal; }
or
html[enforced-dir="ltr"] * { direction: ltr; block-flow: vertical; }
or any other form of enforcements available in CSS, e.g.
!important in UA's and user's sheets.

That would be close to "dirty hack" of course but if you do need
this for your user's good ...
