Need some assistance creating a security rule to block UDP 443 outbound on my PA-3250 firewall.

Is there something unusual in the setup or? It should be fairly simple to block all outbound UDP/443 traffic if that is what you want to do.
Objects -> Services
Add new service for UPP/443 traffic, i.e.:
name=UDP443
Protocol=UDP
Destination Port=443
Policy -> Security
Add new security rule:
General->name = Block_UDP443
Source->Zone = Trust (or whatever your internal zone is)
Destination->Zone = UnTrust (or whatever your WAN zone is)
Service/URL Category->Service = UDP443 (added above)
Actions->Action Setting = Deny
Or do you actually want to block QUIC traffic?
Policy -> Security
Add new security rule:
General->name = Block_QUIC
Source->Zone = Trust (or whatever your internal zone is)
Destination->Zone = UnTrust (or whatever your WAN zone is)
Application->Applications = quic
Service/URL Category->Service = application-default
Actions->Action Setting = Deny
