Have you posted a hypothetical example that will be scaled up somehow, or is
this the actual problem? If it is the actual problem, why not just
explicitly combine the desired terms?

In[2]:= L1 = {a,b};

In[3]:= L2 = { { {f,g,h}, {j,k,l} }, { {m,n,o}, {p,q,r} } } ;

In[10]:= {{L1[[1]]L2[[1,1,1]],L1[[1]]L2[[1,2,1]]},{L1[[2]]L2[[2,1,1]],
L1[[2]]L2[[2,2,1]]}}
