LN privacy question

What does it mean final hop? When I try to use that function Zeus only proposes me my channels. I was expecting to be given a list of peers the receiving node is connected to.

I'm using Zeus, Thunderhub and RTL but I never found out how to configure the minimum amount of hops in the path? Where do you specify that? I can only chose the first outgoing channel and a maximum fee I want to pay.

I'm on LND by the way. Maybe it's related to that? I should probably try c-lightning 

Do you have a reference for that? I never heard of shadow nodes so far.

A solution to this problem is to route all your LN transactions through a public node that you secretly control so that you can be sure that it will never cooperate with other nodes to harm your privacy as a sender.

Blinded path is a proposed solution to receiver privacy from what I understood.

Privacy wise I don't think it really helps though. It's probably even worse since having more transit nodes increases the risk that every node will cooperate in at least one path.

I often read that the lightning network has good sender privacy but since public nodes can be contacted and possibly pressured to share the details of their part of the transaction, a motivated attacker could backtrack the transaction from the receiver to the source utxo, right?

Does having a longer path increase your privacy lowering the risk of the nodes colluding to reveal the originating utxo?

Is there a tool where you can specify a minimum number of hops for a transaction? So far in my experience my node will always pick the shortest path (usually 2-3 hops) and I never found a wallet that lets me chose longer paths.
