Hey Rob,
If you know enough about regular expression then it's doable:
^(?>(?:(?!Your_Pattern_Here).)+)$
This won't manage blank lines from the “Process Lines Containing” dialog though.

That's because -v is a command-line-switch for the `grep` command-line-tool –
it's not a syntactical meta-character for BBEdit's regex library.
This task can be accomplished quite easily using BBEdit's Text-Filter feature.
This filter will delete any lines NOT containing the pattern:
#!/usr/bin/env bash
sed -E '/Your_Pattern_Here/!d'
This filter will print only lines NOT containing the pattern:
#!/usr/bin/env bash
sed -En '/Your_Pattern_Here/!p'
If you want a little bit of UI and can deal with a literal-string then you can
roll-your-own:

tell application "BBEdit"
set ddTextReturned to text returned of (display dialog "Enter your text:"
default answer "" with title "•• Find Lines NOT Containing ••" giving up after
30)
tell front text document
set myLines to contents of lines whose contents does not contain
ddTextReturned and contents is not ""
end tell
if length of myLines > 0 then
set AppleScript's text item delimiters to linefeed
set newDoc to make new document with properties {text:myLines as text}
end if
end tell

Run it from the Script Editor.app to see how it works.
