I have not. I run wvdial from a terminal and when I'm done I Ctrl-C
in that terminal. The Ctrl-C always shuts down pppd properly.

Nope.

I haven't needed one, but you could right a script that will kill both
wvdial and find the PID of pppd and kill it too, if it exists.
Something simple run from root, or preferrably sudo:
<bof>
#!/bin/sh
echo "Stopping wvdial..."
killall wvdial
echo "Checking pppd..."
PPPD_PID=`ps axww | grep pppd | awk '{print $1}'`
if [ "$PPPD_PID" != "" ]; then
kill -9 $PPPD_PID
echo "pppd process killed"
else
echo "pppd already dead"
fi
<eof>
Bear in mind, this bitty script is quick and dirty and needs testing.
