shows, \PassOptionsToPackage after \usepackage is silently ignored.
I.e. if LyX were to use it, this would not prevent the error but only the
error detection.
That's clear, but \PassOptions... at least gives you an opportunity to
put some more options, and the result, or the lack of the result can be
seen in the produced document.
So, first both LyX and user can \PassOptions..., LyX will or will not
call some package at the end, in the latter case user will call it herself.
\documentclass{minimal}
\PassOptionsToPackage{utopia}{mathdesign} % set by LyX
\PassOptionsToPackage{something_other_than_utopia,greekuppercase=italicized}{mathdesign}
% set by user
\usepackage{mathdesign} % called by either LyX or user
\begin{document}
$\Gamma$
