They did say that they are testing the neutral and evil aligned companions first, yes, and Helia is indeed a werewolf (though the possibility that she's been scrapped entirely has been floated, since the data mine for her hasn't had any updated information in months).
That said; Alignments as given for sapient cretues are "for the most part the ones adventurers will encounter will mostly be like this" - if it's not a deeply intrinsic thing as part of their essence (celestials and fiends primarily), then that general rule is not an absolute, and individual instances of specific creatures may vary. Lycanthropes specifically do not fall into this category of 'essential' alignment - different species of were creatures have strong trends towards various alignments, in fact - were bears are commonly good-aligned, or example. Werewolves are most commonly CE, as written, but it's not an essential trait, and individuals can choose otherwise. This is especially true in the case of adventurers themselves, who are by general definition unusual. Astarion, for example, is not evil *because* he's a vampire spawn - he's evil because of who he is and how he behaves. Helia may be a werewolf, but she's also an adventurer and her own unique person, so we won't know how she aligns until we meet her; it's quite conceivable that she deliberately defies the way her curse inclines her, if she's slated to be in with our good companions.
Ah, but doesn't this mean all these characters are essentially cliches?
"A Sharran priestess would normally be evil, but ours is not."
"A person who enters into a pact with a devil is normally evil, but ours is not."
"A werewolf is normally evil, but ours is not."
And so on.
Very convenient, trite, and pathetic to me.
