Whenever I remove a device’s IP address on the machine itself and restart networking and/or reboot, the old IP address does not disappear from LibreNMS’s IP address inventory. When does LibreNMS remove device’s old IPs?
This worked for me, I hope it helps you.

Sorry if I’m misunderstanding, but what does this have to do with old poller nodes?
Hello, in my case the same thing happened to me and I had to enter the database to eliminate these old nodes.
From the link I share, I have used the commands indicated there to enter the database and delete this information.
DELETE FROM pollers WHERE poller_name! = ‘Librenms’;
In this example it refers to the “pollers” table, but in your case you have to locate the table that stores the nodes and manually delete this information.
There may be another simpler method, but in my case I found this one.
I don’t know if it applies to your case, but it helped me.
David.
