How likely am I to be audited if the Bank files a form 8300 for a large cash deposit?

My mother is on hospice watch and I'm preparing to deal with estate / will / property issues.  I believe she has a large sum of money exceeding $10K in her safe.  I know of FinCEN  / IRS form 8300 requirements if there is a large cash deposit of $10K or more, and it just feels silly to run around depositing cash deposits at other banks which might even flag structuring.   Is there a way of making this deposit that can bypass the bank reporting it? I'm not a drug lord.  I may need that cash to pay for estate-related expenses.
