When does a non-US owner actually need an ITIN, and how long does it take?

Only when you personally have a US federal tax purpose and cannot get a Social Security Number, for example to file your own US tax return. You apply on Form W-7. The IRS asks you to allow 7 weeks, or 9–11 weeks if you apply from abroad or during tax season (15 January to 30 April). Forming the LLC and getting its EIN do not wait for it.
