> Then there's C7(#11), which you'll often find when C is the IV chord, 'cause the IV chord gets a Lydian scale.. but now I forget how that explains anything.
I'd say it's usually the other way around: if you want to improvise in a Lydian mode, use a 7th(#11) chord on your IV, while improvising; if you're composing, use this chord to hint the interpret to use this scale. And so on.
