Your question, as best as I could tell, is that you want DNS traffic to exit through your VPS node, rather than your client machine.
I posited one reason this could be happening, and additionally, a similar setup that provably routes traffic through the VPN based on the method I described.
Nobody in here is obligated to help you, I gave you a couple threads to pull on to resolve your question, so maybe consider accepting it graciously, rather than being obstinate.
Is it the word “lawyer” or spending some small amount of money?
Lawyers are bound by law and an ethical code to conduct business in a particular way. They also tend to have support infrastructure and continuity plans that private individuals do not.
If making sure something actually happens is important to you, this is the best option.
