OpenPhil has been fairly transparent about this, stating it in their grant report on OpenAI (and I believe I’ve seen it elsewhere).
Back in March 2017, in a writeup about the $30M grant recommendation to OpenAI, OpenPhil were transparent about HK (then-CEO of OpenPhil) being engaged to DA’s sister, while DA was a researcher at OpenAI and also a technical advisor to OpenPhil and living in the same house as HK. (This was before the two siblings were appointed to VP positions at OpenAI, which I’m not aware was ever publicly reported by OpenPhil).
As you mentioned in your comment, OpenPhil changed their policy about publicly disclosing relationships. If today OpenPhil faces CoI situations that are similar to the ones they faced when recommending that $30M grant to OpenAI, they may not mention those CoIs publicly at all. It is also possible that the relationship disclosures about the $30M grant are publicly available on OpenPhil’s website today only because they were publicly discussed prior to the change in OpenPhil’s policy (I don’t know whether they were). Quoting from OpenPhil’s Relationship Disclosure Policy:
Previously, we also included relationship disclosures in our public grant writeups. As of August 2017, we generally no longer do so, and we have removed the bulk of historical disclosures from our website, though we have left a few in place where they had already been discussed in other public fora or were important to understanding the basic case for a grant. This decision was a result of our evolving thinking on what information is important to share publicly and our view that some disclosures seemed to unnecessarily infringe on the privacy of our staff and grantees. Given these considerations, while we no longer publish relationship disclosures by default, we may do so when we think it would help others learn from our work and maximize the impact of their own giving.
