Why cant you use the MediaWikiSite class to get a site reference, call
->getLanguageCode() then make a language object and use the language

Indeed, this is the best advice for this case. Just to expand on it,
since there are several non-obvious steps:
use MediaWiki\WikiMap\WikiMap;
$services = MediaWiki\MediaWikiServices::getInstance();
$wikiId = WikiMap::getWikiFromUrl( 'https://en.wikipedia.org/' );
// $wikiId is a string like 'enwiki' or false if the URL isn't known
$site = $services->getSiteLookup()->getSite( $wikiId );
$langCode = $site->getLanguageCode();
// $langCode is a string like 'en' or null if it's not known
$lang = $services->getLanguageFactory()->getLanguage( $langCode );
$dir = $lang->getDir();
// $dir is a string: 'ltr' or 'rtl'
This is a very obscure corner of MediaWiki, it took me a while to get
this working. I'm not even sure what is the division of responsibility
between WikiMap and SiteLookup.
Each wiki in a wiki farm knows a little bit about every other wiki, but
only a little bit. You can use these classes to look up the language
code or format links, but not much more than that. It doesn't know all
of the configuration, so if you ever need e.g. the list of namespaces on
the other wiki, you'll need to fall back to doing API requests to the
'siteinfo' API or make up some configuration of your own.
