Hey, I have enabled LLDP on a WS-12-250-AC...however I can't find a way to access the information. Nothing in the GUI and via SSH I do not see the LLDP information anywhere either. I also enabled CDP and UDP but none seem to be working / storing the information anywhere.

Tools, Discovery...

The checkboxes for Cisco and LLDP tell the switch to send packets to neighboring switches. If you have the discovery tab checkbox enabled then go to Tools, Discovery to see neighbor switches (if they are sending discovery packets).

Is there a way to see the neighbors from either the command line or via an SNMP query?

sakita is correct.

By enabling the LLDP or CDP protocol the switch will notify neighbors or discovery tools for that protocol of its existence.

In the discovery TAB it will only report a device once by the first protocol it sees. So for sake of argument the switch sees another switch that has UDP, CDP, LLDP enabled whichever protocol it sees first is the one it will report in the Discovery Tab

No, I do not believe so but have asked Eric to confirm.

My thought is that if it is in the Interface it will typically be in JSON file on the backend as well?

From the command line, "cat /tmp/discovery.json"

File is not there, I have confirmed that an upstream device DOES have CDP / LLDP enabled.

Is it possible I need to reboot the device?

The file isn't there unless the 'Discovery Tab' checkbox in Device Configuration is checked...

cmdline

cat /tmp/discovery.json

...I verified this behavior by turning the checkbox OFF and then rebooting to make sure the existing file was deleted. Turning it back ON did NOT require a reboot.

Here is an exact copy/paste of the configure for each being "true".
