Hi NWAdawg
lxsession is not installed by default, so I have been thinking about the most elegant way to overcome this. If I was facing this issue myself, I am not, but I can imagine, I would create a new symbolic link in my personal bin directory named "lxsession-logout" and have it pointed to the existing openbox-logout script/command.
A personal bin directory should have been created by default, if you have deleted it, you will need to recreate it and restart your session. Next, enter the following command to create the symbolic link:
ln -s /usr/bin/openbox-logout ~/bin/lxsession-logout
Any call to lxsession-logout should now invoke the default openbox-logout script/command.
Hope this helps 
Note: If you do not want a personal bin directory, you could always create the link directly in the /usr/bin directory:
sudo ln -s /usr/bin/openbox-logout /usr/bin/lxsession-logout
