The file you are looking to edit is the smarty template entries.tpl. That file has 3 different entry footer options:
Below entry
Below entry title
split (part below title, part below the rest of the entry).
None of these has a link to delete the entry. The fact that you say it comes after the freetag categories leads me to think it is the output of an event plugin.
The edit entry link is the smarty value {$entry.link_edit} - I do not know if we have an equivalent of that to delete an entry.
it was down to another event plugin, the one that adds the delete option for admins... i couldnt work out how to make it appear lower so just uninstalled the plugin in the end. I feel so defeated
Only way to get exact placement of that output would be to smartify the plugin emitting the delete link... the freetag plugin has that as an option. You could modify bulletproof's entries.tpl file to emit the freetag output after {$entry.add_footer}.
