There are many wallets that let you connect to their Tor which they have on the wallet but I do not believe in it. I prefer to connect to Tor instead in a way that if the wallet does not connect to the Tor, it will not work.
But many bitcoin wallets nowadays have Tor comes with them. Do you trust it? I do not think I can trust it than connecting to the Tor provided by the Tor project.
Is the Tor that comes with the wallets are also from the nonprofit organization Tor Project?
It will just create false sense of security since somehow people can still see the transactions you have made. Also I'm not comfortable to connect my wallet on any platforms knowing there are so many scams in internet.
I'd rather choose not to connect it and will not care much about those things since I believe that we will be more safe if we are not curious on everything.
If you also mean about those privacy focused wallets which is created by TOR project then yes they are non profit organization behind the TOR network.
