New skill- Feign Death. Requires Hunting and The Will To Power. Expensive to put it out of reach of brand new characters who have nothing to lose anyway. Perhaps around the cost of Trespassing?
Once Feign Death is trained wildlife will not attack the hearthling while he/she is unconscious. Basically the W3 animal behavior as buyable skill. I'm not suggesting a hearthling be able to feign intentionally, just that after its trained the animals won't use murder so a KO'd player can try to port to HF or get up and make a run for it.
Speaking as someone who has never been killed by the new "dangerous" wildlife, I've still had a bunch of my villagers killed thanks to lag mid-combat while hunting or meeting a bear more than a minimap away from water. There's many players who are advanced enough to lose a lot of progress due to dumb animal luck but not advanced enough to have the 150~ combat skill needed to actually fight something like a bear. I think it would be helpful if there was a halfway point of protection, not enough to fight but enough to escape.
I've seen the previous suggestion for Stealth affecting animal aggro ranges, but I think this is simpler.
