Each can be seen as using a tool to add false legitimacy. But ultimately they are just tools.
Edit: to clarify, people were judged by the clarity of their handwriting in the past and these tools made that impossible. Similarly, LLMs spackle over higher level language issues.
These things are not remotely comparable.
Example: Donald Trump did not write Art of the Deal
All these tools provide leverage to the author, but only one of these tools provides non-deterministic leverage.
It's not like typewriters -- in a written work the content is the entire point, not the handwriting. So unlike previous tools, this one is replacing you for the part that actually matters.
People use these tools for a variety of reasons (as diverse as people’s experiences). One can use an LLM to help express a perspective or develop and opinion (very important for those who struggle to communicate), or one can fake a picture or voice for fraud, or a million other purposes. It’s just a tool. How it gets used is about the people, not the tool.
