A comma after "LLC" is not grammatically necessary (Authority: The New York Times Manual of Style and Usage by Allan M. Siegal and William G. Connolly, Times books: New York. 1999.
The comma goes after the business between the name and the LLC. Business Company, LLC
No, there usually is not a comma after LLC. However, it will depend on the business and how the company was registered.
Unless the company specifies its preference for a comma, none is required to set off "LLC" from the company name. In contrast, an "Inc." is usually set off by commas. But this is unnecessary, and according to Associated Press Style, incorrect.
Business owners register LLCs with state, rather than federal, agencies, so LLC naming requirements vary somewhat from state to state. There is no state that requires the use of a comma in the name.

No, unless that's what you want. If you want to form your own LLC, you can either name it "New Company LLC" or "New Comapny, LLC." Those are two different names. Whichever one you put on your filing paperwork, spell it the same way from that day on. If you change your mind later, you will have to make a new filing, or there will be legal implications (i.e. you can be held personally liable if you sign for a misspelled/nonexistent business). So whether you spell it with or without comma, is up to you, as there is no universal agreement which style should be used, but be consistent. If want to write to or about someone else's LLC, you will need to look it up. For example, there is "LearningExpress, LLC" (with a comma) and there is "American Domain Names LLC" (without a comma). While very unlikely though because of the confusion it can cause, someone could file for "ABC LLC" and some else could file for "ABC, LLC" in the same state (which may or may not accept both filings).
