Earlier quoted context omitted.
Both Wikipedia and various telecom bids / contracts I found listed it as ' Starlink Services, LLC'. Which is owned by SpaceX, but it appears to be a separate company. The entity I found in an Oregon bid was registration #4503816 in Deleware.
It is not a separate company in any meaningful sense. The job listings for Starlink all clearly say you are working for spacex and you are granted RSUs in spacex. “Starlink services” was probably legal prep in case they ever wanted to sell it off if it flopped.
The body of the evidence as far as I can tell suggests Starlink is a separate company even if employees that produce much of its products work for a different company.
