The license is very clear: obviously the dynamic library that is loaded would have to carry the notice somehow.
If you consider inclusion of symbol names into the application binary to be a "redistribution in binary form" of LLVM, then your application would need to carry the notice. I would recommend either consulting with a lawyer to decide whether that is the case, or to just include it to be safe.

Something like that is fine, but you need to include the copyright notice as stated in the license. I'm not going to weigh in on whether (or not) the binary is being distributed in your case, check with a lawyer.
