AFAIK, multiple routers showing up in a single-hop in traceroute response is a sign of packet-by-packet load balancing, not flow based.

Not necessarily, and in most cases probably not a fact. Don't forget that standard UNIX traceroute uses UDP where the destination port of the probes is increased for each subsequent probe. So per-flow balancing hashes taking L4 header information into account will see each traceroute probe as distinct "flow".
