White vamps hit people with overt supernatural emotional manipulation all the time. Lara does it to Dresden in half of their conversations, including at formal events where he was acting as a representative of the council.
They don't go all the way to domination, but the supernatural world clearly considers not being able to make a certain basic level of will save as a basic requirement for going out in public.
This is also fairly back alley as far as these meetings go, pressing at least a little would be unusual.
I do not recall this being a thing. Whites? Yes. Lara? No.
Dresden being a horndog in the earlier books is a very real thing that is called out in the narration, and the passive impact of Lara Raith boosting her allure when entering a room is explicitly signposted in Blood Rites.
But I do not recall any diplomatic occasions where Lara has ever knowingly, actively projected overt emotional manipulation at Dresden, or someone else she's supposed to be meeting for formal talks. I cant vouch for informal social events, mind; I dont think we saw any of them with Lara onscreen.
Her control isn't perfect, but Dresden has never worried about this to my recollection.
The only time I recall its been ever pointed at him was in the Raith Deeps when he asked Lara for it to boost his spell casting.

The supernatural world certainly considers a minimum level of passive mental and emotional defense a basic requirement for going outdoors. But they clearly differentiate between passive boosting of your own allure, and actively fucking with other people's heads. Especially at a diplomatic meet.
And Lara Raith explicitly has too much on her plate to be pushing the boundaries now, even if she wanted to.
Nor would she be doing it in front of three people.
Big brass ovaries on that woman, but she hasn't lived this long by taking unnecessary risks.
This has come up several times now.
Regardless of what the charm says in practice we've had multiple instances of reflexive not being good enough. Things like that warning that Mab would have rolled us if we hadn't had it up before she even started talking, that nazi sorcerer's forget-me field.
We've also seen that when it does work we still visibly grapple with whatever we're guarding against before shaking it off. Which doesn't have a mechanical effect on terms of being influenced, but is notable in a social situation.
When talking to vampire I think it's better to show no vulnerability at all; not just tough enough to resist, but inedible from the start.
There is the early onscreen weirdness with Gorfels, yes, but that's it.
We preemptively had IPM active rather than check if it would activate on its own with Mab, which is not the same thing as it not being able to activate reflexively. If you want, we can clarify with the QM.
Anyway, these are different circumstances.
Lara Raith is not our friend; might be an ally, and is an important factor among the people who dont want the world to die, but we aren't friends. At least not at the moment.
However she isn't going to ask her only brother to host a diplomatic meeting where she intends to flagrantly break the basic customs of diplomacy among the night people. Especially not when the people she is fucking with have sufficient connections and ability to make an issue of it.
And she is most definitely not going to go out of her way to antagonize an outside actor of unknown power and allegiance when she's supposed to be trying to flush out Outsider-linked traitors in her own house and Court.
She's not Constantine Raith, she's the smart one.She isn't going to start a fight on two fronts.
I mean, she's sitting across from two martially-talented Exalts with no escort or protective detail in sight.
And Molly is wearing fucking chainmail.
That is in itself a show of good faith, and not a woman here to test boundaries.
EDIT
Now that I think of it, we should have brought Mouse.
Maybe we'll borrow him as additional security for the meeting at Mac's place, just to see her reaction
