I have a Moto G4 (Athene). Now that LineageOS has stopped supporting my device?...

[Kwipper]

... should I continue using LineageOS 14.1 install on my phone, or should I find a new rom? If so, which one....or should I revert back to stock in the meantime? I am looking for some guidance as to what to do from here on.

I think there is an unofficial version of Lineage that is being maintained. Supposedly, the official Oreo update is coming soon so maybe going back to stock may be best.

You are using a nougat based ROM ,I think you should probably go for pie/oero based ROMs in our forums. And if you like it just stick to it, because it is been frequently updated with latest security patches.
PS: But make sure you fulfill all the requirements before flashing it. Because anything can happen,any time
