Can be set as a buffer local variable.
True, but not relevant to the OPs query:
Is there any way to excude the empty `\title{}` command?
And if you browse thru org-latex-template, you will see that
"\\title{%s%s}\n"
is hard coded. The value of org-latex-title-command has no effect on that
part of the template.
So, the OP can either use a filter as I suggested or write a derived
backend supplying a different template transcoder that drops the string
quoted above.
