/usr/local/touch/MultiTouchPlatformHelper
isn’t an Apple thing; on a fresh install of macOS 10.13,
/usr/local/
is empty:
$ ls -lh /usr/local/
$
You’ll need to track down how that software got installed and talk with its author. You might be able to make some headway by dumping the code signature of the program. For example, on my day-to-day work machine I have the BBEdit tools installed, and I see this:
$ codesign -d -vv /usr/local/bin/bbedit
Executable=/MyApplications/BBEdit.app/Contents/Helpers/bbedit_tool
