John Mueller explained that having a private whois does not possess any effect on Google ranking. It does not change the way of trusting a site by Google.
John Mueller was questioned about the Whois information affecting website Trust and Authority.
it doesn’t change anything.
making a domain registration private doesn’t make the domain a part of a link network.
From SEO pov, Does keeping WHOIS information public help in website Trust and Authority? (Google itself is a registrar and can access the domain information of any website)

So Google doesn't use information from things like WHOIS to root out link networks and those sort of things?

Since 2005, Google is a domain name registrar, and the thing that matter to SEOs is that it having private or public whois data on the domain name effects ranking, to which the big answer is no.
