The think is that O(m*s) can actually be huge!

For a 256 alphabet and supposing that a pointer per entry is enough, it results in 1KB per needly byte. Three orders of magnitude bigger than the needle size.

Admittedly, that is a worst case scenario as in most cases, the transition tables collapse into just a few exits per state and can be represented in more efficient ways. But I don't know if the OP case fits into that "most cases".
