I've heard the logic of "a test is only good for the day the blood was drawn" argument. It's a copout. With PCR-RNA testing, it is highly unlikely that a male would become infected AND have his viral load become so high within the 30 days that he would be infectious enough to transmit the virus to a sex partner.
You have a question to ask yourself. Is this director guy rationalizing, because he wants to save money and hassle... or is he making these statements because he believes SO genuinely that HIV PCR-RNA tests are such a crock.
In answer to a couple of your questions... unfortunately, there are very little, if any, precedents set for many of your questions. Government branches are writing laws as they go, and your director would be operating in Seattle, not Los Angeles County, so he would be subject to Washington government health branches and their decisions.
Is unprotected oral sex risky? With a person who has a LOW HIV viral count - it is VERY low risk - almost negligable. However, without testing and simply relying on condoms, you would not know that they male didn't have a high HIV viral count. And the higher the count, the more dangerous even a blowjob becomes. The amount of HIV in precum from a male with a high viral load could indeed be enough to infect a sex partner - especially if they had compromised integrity of their gum tissues (from something as simple as brushing their teeth).
On a personal note, I'm not sure if all of your questions should be from a "could we get sued" standpoint. Maybe a couple of them could be from a "could I sleep at night if I financed a project that I suspected was dangerous and someone ended up getting infected?" standpoint.
