There's a missing page before she fell down.
The guy who hit her wasn't the one who rushed first, he was stopped but the guy behind him rushed towards her. That guy hit her with a riding crop. She tried to set up a barrier to defend but her magical power ran out and it hit her on her arm. This would later reveal the secret she tried to hide.
The traders/merchants took their pregnant female wolves. After the wolves got them back, they left.
They were detained and their punishment would be decided in the next territory they're moving to since the case doesn't have a precedence so they don't know how to decide the punishment. Severe punishment might be avoided but the compensation they have to pay would be enormous. That's as far as the manga raws I read, not sure about the novel.
Ballsack and the other boy was kneeling facing grandpa. Ballsack got warned to never approach Tia ever again or his qualifications as a Lombardy will be questioned. Other boy was teary eyed and scared, but Grandpa said he did nothing when Ballsack was swinging his sword at Tia so he is no longer qualified to hold a sword, no more sword training for him. They left but while other boy was scared and crying, Ballsack was angry and wanted to torture Tia more. While on his way he got tripped by the twins and threatened. Such lovely yandere twins. Ballsack's daddy then rushed to Grandpa's office while Grandpa was handling stuff at his desk. He slammed his hand on the table and was angry at Grandpa.
