If you reduce (with Lucy or on the /etc/config DHCP file) the lease time to anythin < 12h odhcpd don't affect any lease to any client (and no more IPv6-PD to any downstream router)
tested on many routers (QCA, Rampis, X86_64) with OpenWRT > 20.x (21.02.0-rc or any 21. snapshot)
reproductible :
yes, with any fresh install
no need to connect the WAN side
public scope not even needed, LUA is enough to reproduce
Under NetWork / Interface / LAN / DHCP Server set the Lease time to anything lower than 10h
on any LAN host : do an IP release/renew => you loose the GUA address
on any downstream OpenWRT router : restart the WAN interface => no more IPv6-PD on the WAN iface
