Branch profit tax applies if you have ECI only. If the US LLC is owned by an individual, then there is only tax on the ECI.
But if you have ECI and the US LLC is owned by a company and you transfer money out to the owner of the US︀ LLC - then the branch profit tax applies. It's similar to a withholding tax.
Imagine that a UAE company owned a a US LLC that was operating a restaurant in︁ Miami (no state taxes).
Scenario 1:
The US LLC is taxed as a corporation and︂ makes a $1M profit. It pays the 21% CIT (hope I'm correct about the federal︃ CIT rate). The remaining $790k are paid as a dividend to the parent company. There's︄ no tax treaty, so a 30% withholding tax ($237k) applies. Only $553k can be paid︅ out to the UAE parent company.
Scenario 2:
The US LLC is taxed as a︆ disregarded entity (tax-transparent) and makes a $1M profit. There's obviously ECI (it's a restaurant), so︇ the profit is subject to the same 21% CIT. But except for the ECI, it's︈ tax transparent, so there are no dividends to pay out, so withholding tax on dividends︉ doesn't apply. Without a branch profit tax, the after-tax profit of $790k can be transferred︊ to the UAE parent company without any additional tax withholding.
That's what they wanted to︋ fix because scenario 2 suddenly came with a massive tax advantage. So the branch profit︌ tax was introduced, which simply puts the same withholding tax (additional 30% tax) on any︍ money that is transferred out to the parent company, like a dividend. It's not a︎ dividend though, that's why they call it the "dividend-equivalent amount".
So if you have ECI,️ it's a double whammy situation if the US LLC is owned by a company instead of an individual.
Just google it, there's a lot of info about it, e.g. this:

However, there's also at least one positive with a company owning the US LLC: You can avoid the US estate tax.
If you die and you're the direct owner of the US LLC, then there would be US estate tax, at least on all US assets. I'm not sure if the value of the LLC itself would also fall under that.
If you die as the owner of the foreign company owning the US︀ LLC, then the US LLC wouldn't be impacted at all.
Yes, that's the theory. And I've heard that it works perfectly fine like this for︅ a lot of people.
However, if you have US business clients, they only see a︆ US company. And they may send a form 1099 (if I remember correctly), because that's︇ what they would have to do for a US supplier.
They will send a copy︈ to the IRS and say "This US company is doing business for us, a US︉ client". It's not your client's job to assess your tax status. You're a US supplier︊ as far as they are concerned.
From what I understood, the purpose of this is︋ to make it harder to evade taxes.
Basically your client reports your income to the︌ IRS for you "We paid this US company $50k for their work".
Then the IRS︍ will notice "So this US company earned $50k from this US client.... Why didn't they︎ pay any taxes?" (Note that the company being owned by a non-resident alien doesn't automatically️ mean there was no ECI, as in scenario 2 above.)
So now the IRS may come looking for that tax. Or, to put it simply, they may simply assume/claim that there was ECI and then you would have to fight them about it.
And I guess in states like California, the IRS may be extra aggressive.
Yes, it sounded weird for me as well, but that's what both a very reputable (=expensive) US tax lawyer and also a CPA told me. They said it might make more sense to use the US LLC only to market to US clients and then bill from a foreign︀ company (and not the same company that owns the US LLC).

You see that your US clients will have to send︂ them. And then the IRS may eventually come asking why you didn't pay the tax.︃
Maybe they will accept your explanation that what you did wasn't ECI... or maybe they︄ won't. I have no real life experience, so I have no idea how big this︅ risk is.
I've head of a lot of people doing this without any issues. But︆ the tax lawyer really didn't think it's a good idea. (He did think it's a︇ good idea to use a US LLC to bill non-US clients, however.)
