Surtur and Odin at their peaks are by far the most powerful Marvel characters aside from Thanos with IG and Dormammu. Entirely different tier of characters that bear no relevance to this team.
Mantis has to get close to do that. Hela is a lot more dangerous than Thanos up close because she can omni-directional spam her weapons on a whim that doesn't rely on making a closed fist with an external object that can be removed. Strange's BFR is a possibility but also not a sure thing because Hela has to some degree the ability to teleport herself.
Saying he is immune when we see Hela’s projectiles affect him shows he isn’t immune. She lacked the power of the means to defeat him.
So saying she is unbeatable isn’t true despite your semantics. We see her beaten on screen and know she was beaten prior to.
We have strange, portals, misdirection, etc. we see many characters get the jump on her in the film that isn’t half as formidable as the team that challenged Thanos on Titan. She won’t even come into play until Hela is vulnerable to such an attack. Tony Stark and Dr. Strange are pretty good at this fighting thing.
Hela can’t just come back on a whim. She’d lose the battle if she ends up in a strange portal.
