I like the graphics of
#1 and the text of
#4 . But I would kern the text to make the ends line up, so the text fills a rectangle nicely. Also, I wouldn't put "LLC" in the logo - it's kind of extraneous info, and some day you might change to a non-LL corporation.
You can also think of it as 2 components, a graphic component and the text component, and they can each stand individually or combined, and combined vertically or horizontally. Designers usually work out identity/branding systems that can be expressed in different ways and maintain the identity.
