Here's the only recent article I can find on the actual case.
Calls are growing louder for Nashville police to release trans school shooter Audrey Hale's writings, even though an investigator has said they are 'rantings' linked to mental health problems.

Evidently, LE is indicating the journal writing are not manifestos but the diary of a madperson.
From link:
In a television interview, David Rausch, director of the Tennessee Bureau of Investigation, said he had studied Hale's writings and that it was 'mischaracterization' to call them a 'manifesto.'
They feature none of the 'ideological expressions' found in other mass killers' screeds, he said, such as the 35,000-word essay about the collapse of industrial society by 'Unabomber' Ted Kaczynski in 1995.
'One is specifically a plan, and the other is some journal-type rantings,' Rausch said.
It's really unfortunate mental health issues you can see as you read through the journals.'
