Make wolves actually fear llamas, or make tamed ones guard them.

|| (Context paragraph- skip to bottom for actual suggestions)
Llamas are awesome- 150 storage slots per caravan, plus style points, I love them.
However, there's a major issue I've personally been facing that's quickly becoming extremely annoying- every time I turn my back, they've picked a fight with another random wild wolf, and usually a llama dies. It's severely irritating, and as much as it makes sense for the llamas to spit at wolves because of the "guarding the sheep" thing, it just ends in a dead sheep and llama with the way it works right now, since wolves seem to ignore their fear of llamas when they're angry at sheep.

So, I have some ideas on ways that could help this issue, any of which being implemented I feel would be a huge improvement:

1. Make wild wolves actually run away from llamas after being spat on, instead of attacking back. This would make llamas feel actually impactful in their job as protectors of sheep.

2. Perhaps make tamed wolves able to guard the llamas in caravans. This would make guard dogs an actual feature, and it would totally add to the style of a travelling caravan.

(also 3, please make llamas not kill each other when one spit hits another llama, it's so stupid)

Of course, any other ways to solve the issue would be awesome to see/hear as well, and I heavily appreciate any consideration of these ideas.
