Yes - based on your information - filing is required.
Unless you elected differently - the LLC with several members is classified as a partnership.See instructions - page 3
Who Must File -- Domestic Partnerships -- Except as provided below, every domestic partnership must file Form 1065, unless it neither receives income nor incurs any expenditures treated as deductions or credits for federal income tax purposes.
Thus because your partnership had deductible expenses - filing is required.
If these are deductible expenses (not capital expenses) - which generate loss - then - you woudl need to have K1s to pass these losses or deductions to partners.
If these are capital expenses which are not immediately deducted - no K1 needed.
Instructions do not set a threshold amount fro income or expenditures...
They also do not have exclusion for certain expenditures as you mentions.Some time ago - filing requirements fro LLCs were regardless of income or expenses... so when the IRS allowed not to file for some LLCs - that was a relief.
As a practical matter - you may consider as expenses paid by you personally and not to file - it is very unlikely that the IRS woudl ever question your position. In this case - you woudl not be able to deduct these expenses.But formally - filing is required.
