LLCs do not necessarily have to be a well known/actual "company"...

LLCs do not necessarily have to be a well known/actual "company" - I think it can just be a legal structure. So it might just be individuals or a group of individuals looking for favourable tax conditions but don't quote me on that I am not a corporate lawyer lol.

See this link explaining why you may want to set up an LLC for investing:

Edit: As suspected, per the above: "LLCs do not pay federal income taxes, meaning that once the owner makes an investment through an LLC, they’ll save money as their tax obligations are smaller than when investing as an individual.As a sole investor, you will pay taxes on all sources of your income, including earnings from stock dividends and capital gains."
