Connector smt footprints seem to need a net associated with them are they useualy gnd or something? What’s a good idea and safe bet just have a net called mount or something and connect them all?

I am not really sure i understand your question. Could you maybe add a screenshot to show what you mean?

My impression is the OP may be referring to mechanical attachment points that provide extra part stability that a through hole would normally provide.

I’m with Rene & Hermit.
I don’t really understand Josh’s post.

In EEschem all unconnected pins should have a “no connect” cross / flag.
In PCBnew, SMT connectors often have pads which are only for mechanical stability and are not connected to any net.

Note: It is a very good idea to design these footprints with Via’s under those mechanical pads. This makes the attachment of the connector to the PCB much stronger.

If this answer does not cover it:
