LTSP clients grab just enough of an OS to basically VNC into the server, so there isn't anything running on clients for you to VNC into. You can set up LTSP to run some apps on the local machine, but the session is still coming from the server. You can ssh onto the client machine, but there is no graphical session actually running on the client. If you want access to the displays on various clients, something like FL_Teachertool is probably your best bet. I'm not sure what it's status is on recent versions of LTSP though.

Yup still lurking. :-)
LTSP4 had a version of X that would support a vnc server module built
right into X. But since LTSP5, I changed fl_tt to work with x11vnc
being launched on the client.

I have docs up how to set it up here

But I think Barry made an rpm that does it all.
