I just checked it... and there is no difference between Good Liv's refusal and Evil Liv's. The dialogues are the same. By the way, it wasn't even necessary to check, because before this there is a check for the state of certain flags, and if the check fails, the dialogue is the same.

And the wording of the refusal itself sounds as hypocritical as possible, because if we assume that this is not nonsense or an error in the dialogue, then Olivia may be hinting that she and Kane do not have a romance, which is indicated by the goldilockdom flag (which we get in the pool scene in 0.8.1), but that's not true, and in almost all of my saves (both good and evil), this romantic flag is active.
Well, let's try to figure it out and look for the logic in it (spoiler: there still isn't any).

Conditions for triggering the scene with Alessa and Liv's VIP room:
goldilocksdom=True and demonessdompath=True or goldilocksdom=True and klmistressdompath=True
Before we continue, take a look at these walkthrough details (season 1):

As we can see, the conditions for obtaining the
k1mistressdompath flag differ from those for demonesses, so formally, Olivia may not be a
demoness,
but she can still lead K1 and kill people of the corresponding rank.
But in fact, this rare
k1mistressdompath flag does not appear anywhere else in the game; I checked every official walkthrough using a quick keyword search. Whereas the demoness flag is much more widespread.
But in any case, even if your
Evil Liv is not a demoness, and you have clearly calculated and made it so that she “only” cold-bloodedly killed a person and became the head of the K1 department, it still doesn't make her a good and fluffy sheep, and it's easy to assume that behind the scenes she actively killed those who fell under her care, as Mercy, the head of K1, did (and still does).
So, even if you calculated everything in advance and by the time of the key choice (the murder of the old man from the wastelands) in K1, Olivia had, say,
6 sisgood pts and
14 sisevil pts (
which guarantees her not getting the demonic flag, but getting K1mistress), she still remains very evil.
Now let's return to why there is still no logic in Olivia's refusal. Such a response makes sense only if Olivia has either a demoness flag or k1mistressdompath, but Kane refused to start a romantic relationship with her (i.e., the flag goldilockdom=False).
However, in the case where Liv is good or even evil
(but not a demoness or K1mistress), such a response simply makes no sense at all.
In fact, an evil Olivia who does not meet the conditions of the VIP scene should have said something like,
“I thought about inviting you somewhere... but I changed my mind. You showed a special interest in me, but you didn't work hard enough to turn me into a complete evil bitch who kills innocent people. So I'm just evil, and Alessia and I will have fun without you, lol". 
The most difficult and unpleasant thing awaits the Good Liv. I have no idea what she should have said here.
According to logic,(which Tess threw out the window), this VIP scene with Alessa and Liv on the GoodDom route shouldn't have happened at all, but! if Liv's refusal was made solely (by Tess) to hint to the players that they are missing some Dom content, then the method chosen was not the best.
And this will only fuel speculation about whether "GoodOlivia" is really as good as she seems, or whether behind the scenes our agent Olivia is cosplaying Mercy and Jules in one person.
