I am finding out, it seems OSPF SR doesn't work properly :(

I have opened a case with FRR and it is currently being looked at/worked on. The link is (https://github.com/FRRouting/frr/issues/12007).

We figured out the problem. So for OSPF segment routing to work we need to enable opaque LSA capabilities. So by default VyOS doesn't have opaque LSAs (type 9, type 10, type 11) enabled. So after checking the configuration for the OSPF FRR template I noticed that the actual command to enable opaque LSAs is broken because it's not in the OSPF FRR template. Once we fix that, we'll have working OSPF segment routing.
It'll be a little while as I am currently doing documentation, but once I put in the PR fix for that we'll have it all working.

Adding PR to fix OSPF opaque LSA and rfc 1583 compatibility to the OSPF FRR Jinja2 template.

OSPF and ISIS segment routing should now have been successfully refactored...at least for now.
Documentation has been updated too.
