Bottom line.
D&D is a game with many things that do not match the "real world".
The Prestige Class has no alignment restrictions period. So per RAW (and the D&D way of viewing such things) - a thrallherd's ability is not inherently "non-good".
Going with dictionary definitions for thralls we should also look at "believers" since a thrallherd also gets those in addition to a thrall. I believe that will give an entirely different perspective than using a reading for one select (i.e., "thrall") aspect of the class ability.
Note that it never mentions domination at all. It talks about a psionic resonation which can most definitely be construed as a non-domination thing.
Resonation usually implies that two things have "similar" frequencies (or something else) that mesh together to make something stronger.
In this case it is not a conscious choice for the thralls (and believers) but something deep within that resonates with the thrallherd and this resonation manifests itself as following.
Note that nothing says that the thrallherd "commmands" his thralls - in fact it specifically says that this ability functions "akin to leadership" - with essentially the only difference being that it is not a "conscious" following.

Thrallherd (Ex): A thrallherd who has just entered the class sends out a subtle psychic call for servants, and that call is answered. Essentially, the character gains something akin to the Leadership featt with some important differences.
Those who answer a thrallherd’s call are not referred to as cohorts and followers, but rather as thralls and believers, respectively. They do not appear because they admire the character and want to serve her, but because a hidden psychic resonance connects the thrallherd and her servants.
