Are there problems that did not get solved for years, or is there no
development because it "just works"?

Do you do this with raw LaTeX (ERT) or is there an inset for the task
(should be easy to write one if its not already there).

For documents that shall work in both, pdflatex and xelatex, it might be
best to have a dummy definition like
\ifxetex
\providecommand*{\L}[1]{#1}
\fi
either in the documents LaTeX preamble or in the module defining the text
inset).

I don't know a solution for this part. It looks like the two engines do
not agree on whether ( and ) are "opening" vs. "closing" or "right" vs.
"left" parantheses.
You may try to create a minimal *.tex exampe file that works with XeTeX
and import this to LyX or try to recreate the correct syntax in LyX
(comparing the View>Source output with the correct XeTeX source).
