If God's words are intended to be taken literally as a way of life, I would think it would be very important that they be exactly correct. If that requires that some writers become vehicles for God's expression for a short period of time, I would say that's a small price to pay.
Praying is not the same as dictating a Bible. Prayer is personal expression. Recording a Bible is creating a copy of someone else's expression, namely God's.
Back when scribes were a thing, they didn't get to put their personal interpretation on what they were writing. They wrote exactly what was there, because it was important that the words were kept the same. This is in part how the Bible survived for a long time. Ditto artists making copies of famous works. If you're employed to make a copy, your employer won't thank you for injecting your own flair. Ditto stenographers, and any other number of professions where the point is to create an exact record of something.
So please explain why it is not important that the words in the Bible are the exact words that God used. Given the amount of quibbling over the things the Bible says, I would argue that the words are EXTREMELY important.
It's similar to witnessing an event, the witness can express what he saw during the events that unfolded, no one tells the witness what to say, he reports what he saw.
