While it's not mixer, you could check
Wasabi Wallet which have built-in CoinJoin and designed with privacy in mind. Both Wasabi Wallet and it's protocol are open source, so you don't have to blindly trust them.
What do you mean by "LE"?
It stands for law enforcement, it's often shortened to LE
I see, i was thinking it stands for Enterprise service/Exchange where it's initial is LE.
