Not sure I understand the vision or goal here, but your brother owns the property individually since it is in his name. Your facts make note that "my brother and I partnered on the purchase of a short term rental property...." doesn't jive with the property being owned 100% by your brother.
As noted by @ThomasM125 , any rental income or expense related to this property is not reported on the form 1065 or form 8825 based on your current facts.
Based on your facts, the LLC manages the property. As such, what gets reported on the LLC tax return is the income the LLC receives to manage the property and any related expenses.
You may need to meet with a professional who can help you sort out the vision and goal and help you get to that goal using the correct entity structure(s).
