Why was Li Yuanba finally struck by lightning? Did he kill someone he shouldn't have killed and die?

I don't think so. The main reason is that Li Yuanba was so rampant that he refused to obey God. It happened to be a thunderstorm. He saw that it was thundering, so he challenged God to lift his hammer, which was just a lightning bolt, so he was chopped to death.

1. Li Yuanba's personality

Li Yuanba can be said to be a simple-minded man with developed limbs. He only knows how to use force, and because of his natural divine power, he says that his martial arts is very high, but he doesn't know how to be a man, and he doesn't know how to behave. Even more, he doesn't believe in ghosts and gods, so such a person is a lawless person, mainly because he was born in the royal family, so no one dares to offend him. Li Yuanba's martial arts is very high, and basically no one beat him at that time.

2. Li Yuanba's whim

At that time, Li Yuanba was invincible all over the world, so he was also a lonely man as snow. It is a great pity for such a military commander to live without an opponent, so he has been pursuing his opponent all his life. Another day when he went out to lead troops to fight, it happened that it was raining heavily and thundering. He thought that God was so powerful that he could be his opponent, so he raised his hammer to challenge God. We all know that the hammer is made of iron, so it is very easy to attract lightning now. It just happened that such a lightning strike hit his hammer, not because he did anything outrageous.

to sum up, he was killed by lightning mainly because he didn't have scientific knowledge. It's unreasonable for him to lift a hammer in a thunderstorm, and it's made of iron, of course, he will be struck by lightning.
