First and foremost, you should study up some more about using a shell
securely.  Always, always, ALWAYS quote your variables when a shell might
be executed, especially if the variables contain external data.  Then try

  | /usr/lib/courier/bin/preline /usr/local/bin/lsv_amin -t "$LOCAL"

lsv_amin will use the compiled-in default for the spool directory if you
supply "-t", so you do not need "-s /path/to/spool" if you use "-t".

I am not sure if you need to use /usr/lib/courier/bin/preline with the
mail; you might want to test that.  From the courier doc:
  http://www.courier-mta.org/dot-courier.html

    When the external program reads the message from standard input,
    the message will NOT have the customary From_, Return-Path:, and
    Delivered-To: headers which are customary for locally-delivered
    messages. The external program can find those headers in the
    respective environment variables. If you have a command that
    expects to see those headers as a part of the message, you can
    use the preline(1) wrapper to add them to the message. For
    example, the procmail mail filter requires those headers.

For reference, I use Postfix and disabled the Delivered-To: in Postfix.

Cheers,
