Try the following:
1 - mount the root file system of your remote machine on your local machine using AFP (and lets pretend it end up at "/Volumes/RemoteMachine")
2 - select the remote-macosx platform and specify the sysroot:

(lldb) platform select remote-macosx --sysroot /Volumes/RemoteMachine
(lldb) process connect connect://192.168.116.187:12345


Let us know how that goes.
