I also posted on OpenWRT Forum since I think it's more to do with some State Table / Firewall / Overload on the IPv6 Stack on their side:
https://forum.openwrt.org/t/ipv6-disappearing-after-a-while-for-lan-clients-troubleshooting-impossible-due-to-lack-of-openwrt-logs/198213
TLDR: once this Issue Occurs, restarting the WAN and WAN6 Interface on OpenWRT seems to solve the issue. Nothing else seemed to help (restarting LAN Client, Restarting OPNSense Router1/Router2).
Once that is done **on OpenWRT Router**, then the LAN Clients can once again Ping e.g. 2001:4860:4860::8888 (Google DNS Servers).
