Sure, West carves state of exception to interdict Westphalian system with liberal international order to justify intervening in others sovereignty but never the less the core scaffold underpinning current global system at UN is based off Westphalia. Which both PRC and Russia and others who wants west to mind their own business is vocal about maintaining. And really if you think LIO can carve exception for intervening in domestic affairs of others, than PRC can carve exception to rationalize intervene in TW (and SCS) anyway. PRC diplomacy and military modernization has been very thorough in preserving full justification to protect her interests under both systems, rule of law or rule of might, which really is how the world works anyway.
> the core scaffold underpinning current global system at UN is based off Westphalia.
Somewhat, but a key change from the League of Nations (which was very Westphalian) to the UN was the UN from the outset grounded Westphalianism as an imperfect expression of, and dependent on, higher ideals such as the right of self-determination, and the UN system has proceeded to flesh out and expand the understanding of the higher principles, and mechanisms for deciding questions of where and when those principles call for deviations from Westphalianism.
Which are result of spectrum of efforts spearheaded by LIO bloc post "end of history" to depart from status quo, that non LIO bloc others have actively defended against. Hence you have non LIO blocs rejecting western NGO consultative status and human rights committees, and in this case wikipedia at WIPO because those are tools weaponized by LIO powers to undermine Westphalian sovereignty. Currently, LIO takeover has stalled thanks to ascending PRC and other non LIO powers learning to outgame the west. Itself met with efforts Trump undermining or stalling these institutions in response. But Wesphalianism is still at the heart of the current order, which many in LIO wants to scrap/reform because it no longer disproportionate represents LIO interests, along with exasperated cries that UN is worthless simply because it now represents more global voices and interests. But until those reforms or replacement occurres, the westphalian framework at UN is still what the global community operates around.

LIO functionally cannot be global organizing principle by virtue of excluding non LIO countries which is vast plurality of current nations. It's a club based off exclusivity not cooperation. Westphalian sovereignty has criticisms and challenges but it's also the minimum standard endorsed by most countries. LIO already has offshoots from global order and operate as a fragments of various multi/mini lateral frame works but it's not replacement for UN where principle of non-interference is still basis for international relations.
