If she's a virgin then what she said to Katie doesn't make her a hypocrite. Leia knows she's good looking plus she's self-confident enough to think she can seduce anyone. She just doesn't need to since she's only interested in our protagonist. She sees her female employees as useful tools to achieve her goals and uses them accordingly, I don't understand how this makes her a hypocrite. However, if she is not a virgin then her attitude towards William is really quite hypocritical. Actually the fact that she wasn't a virgin in the previous version is quite strange and illogical, given all her obsession with the protagonist. I could totally understand if Katie already had some experience but in Leia's case it's weird and doesn't fit her character. I hope that in the new version Ocean will correct this unfortunate misunderstanding.
I don't really see how she can be hypocrite in either scenario, the first you already made a great point. the second, William left with out saying goodbye and with out much of a reason, I don't see how would be hypocritical of her to had sex or casual relationship with other mens int he years that William was away. I don't think that she needs to be or not a virgin, this depends on what direction Ocean wants her character to go, but it certainly does not make her a hypocrite.
It was illogical (given that she has a girlfriend and that we ourselves saw some worm hit on her in the bar), unfair and humiliating, but not hypocritical. We will still have the opportunity to fix the relationship between them(at least that was the case in the previous version). In addition, I believe we will have the opportunity to change Leia's behavior for the better (for example, in the last chapter we can tell her to be nicer to Monica, that's a start). In general I agree with you, at this point in time her behaviour is unacceptable.
Regarding Leia's behavior, I think that's a lot to unpack there and we certainly does not have enough information to do so.
But the fun is trying to understanding. I think that is valuable exercise to trying to understand how much of Leia's behavior is a response to William's. It is difficult to understand the timeline, but we know that at some point William and Leia had a relationship and we also know that young William was not the best William.
I don't believe that William gave Leia the kind of securance that he now gives Miru, that combine with the jealousy nature of Leia created many problems for them. So William had girls trowing themselves at him and Leia had no confidence in him that he could resist, so she in turn was hostile to anyone that showed interest in him.
