There seems to be some misunderstanding about what "manipulation" actually is.
Manipulation does not need to be pre-meditated, nor does if need to involve lying. Sometimes, people can manipulate others without even knowing that they're doing so due to things like poor communication or avoidance.
Manipulation often does involve these things, but at the core, manipulation is when your actions, or lack of actions, have harmful influence over someone else as a means of getting what you want.
This is exactly what Orym did with Laudna. Yes, I do think this decision, in part, was clouded by the fact that Bor'Dor was working for Ludinus and clouded by the fact that he wants retribution for what Ludinus did to his family, but at the end of the day, fully aware of what he was doing, his actions (nodding his head at Laudna when she looked up at Orym to see if she should kill Bor'Dor, something that she very well may not have done had he decided to answer otherwise and remind her of who she is post-Delilah) had harmful influence (Delilah potentially being back due to Laudna giving in to that darkness) over Laudna as a means of Orym getting what he wanted (Bor'Dor dead and Delilah possibly back to aid them in defeating Ludinus).
And yes, Laudna did, at the end of the day, decide to listen to Orym and kill Bor'Dor, something she didn't have to do regardless of what Orym said, but the key aspect of manipulation is INFLUENCE. Orym had influence over Laudna in that moment... if he didn't, she wouldn't have looked to him for guidance, and he decided to make a decision that could potentially harm Laudna as a means of getting what he wanted.
