possible violation of the LLVM-license in commercial product

Dear All,
while digging around in the machine code of a forex trading program I found that they use llvm for their plugin intrastructure. But neither in their documentation nor in the distrubuted files are mentions of the LLVM-license. In my opinion this is a violation of the condition: "Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimers in the documentation and/or other materials provided with the distribution."
Can you please tell me how to handle this case? Does anyone have experience with such cases and is willing to have a look at the present case in detail?
Best Wishes

I’d suggest politely pointing this out to them through some official channel and ask them to fix that. It is probably a simple oversight and they may have included it in a place that you haven’t found. If missing, they just need to add it to some documentation they include (for example).
