The bad news is that unless you're a serious Android tinkerer you're reliant on someone else building the ROM for you, assuming the manufacturer even made the device open enough to install anything full stop.
I could only see one LineageOS XDA thread and it's for a pretty old Android version, so even if you could get it working I wouldn't trust it with any important data as it will still be missing years of security updates.
It's a real shame that a lot of old devices just become ewaste because they're too locked down to do anything with.
