You can look at his trust history and see that one of LL's first sent trust ratings mention that he payed his trading partner late.
So, what? One case does not make a general rule. There will be people who know what Lightlord looks like and don't care. But people who don't know him don't know him. For example people who join his signature campaigns for the first time or people who play in his casinos.
When he takes a month to pay people who request a big withdrawal from his casinos does he also give extra money? I ask because I haven't heard anything about that.
That I do not know. I would assume that once someone requests a withdrawal, their account balance is immidiately deducted, preventing them from gambling with that balance.
Your assumption is incorrect, and shows that you did not read the previous page of the thread, and it was not the first time it was mentioned.
