Re: Is the whirlpool by Samourai (Sparrow wallet and Whirlpool-cli) really blinded?
Sparrow wallet and Whirlpool-cli do not use tor connection management interface.
Where did you get this information from? Sparrow does have a Tor connection management interface, it's bottom left when you're into whirlpool:
Read more about it:
Further, if you have configured a Tor proxy, or are using an Electrum server on a .onion address, communication with the Whirlpool server will be over Tor. Note that you can configure a Tor proxy even if your server is on a local network IP address - Sparrow uses Tor only to connect to externally addressable services. You can verify whether Tor is set up correctly with the status bar icon to the left of the server toggle.
I have never used whirlpool-cli, but I can verify that it uses Tor to connect to the coordinator as well: https://docs.samourai.io/whirlpool/desktop.
