A single router doesn't, but, 1, I was referring to the whole path that THAT router handled, that is, the destination private IP and port in the LAN, to identify a particular device

Two possible problems here. First the router would have to also log the MAC address that the IP address was assigned to. Some routesr do and some do not. Even if the router did log address assignments there is no way to prove which device was using that MAC address at that time. For example you may be able to infer that there were two devices using the same MAC address at different times but you cannot prove which one was assigned a specific IP address at a given time.

it's possible (likely I'd think) that the whole path can be put together from information stored in various device on the along the path.

This can be done for active connections. This is how criminmals are tracked. Routing is very dynamic. So the path for one active connection between two IP addresses may not be true for prior or future connections between the same IP addresses. It may be possible to reconstruct the routing table
at a particular hop in the path between two IP addresses for a given time in the past but not very likely. That information is only rarely logged. For billing purposes traffic between networks is monitored and logged but not individual IP addresses.
