I tweeked my configs a bit more and I think the issue is b/c I didn't reinstall traefik. I removed the hubble.ui.ingress parts and it at least didn't panic.

New locals

locals {
  settings = {
    "orbstack" = {
        "operator.replicas" = 1
        "cni.binPath" = "/var/lib/rancher/k3s/data/current/bin/"
        "cni.confPath" = "/var/lib/rancher/k3s/agent/etc/cni/net.d"
        "hubble.relay.enabled" = "true"
        "hubble.ui.enabled" = "true"
        # "hubble.ui.ingress.enabled" = "true"
        # "hubble.ui.ingress.className" = "traefik"
        # "hubble.ui.ingress.hosts.0" = "hubble.domain.tld"
        "envoy.enabled" = "false"
        # "nodeinit.enabled" = "true"
        # "cni.chainingMode" = ""
        # "cni.chainingTarget" = ""
        # "cni.exclusive" = "false"
    }
}

This works but needed me to destroy before applying
