Yes. There is no may in the instructions so if your opponent Thoughtseizes you and you have only a Forest and a Wilt-Leaf Liege in hand they must choose for you to discard the Leige.
yes, if there is a choice he can make, he must make it.
you're not 'searching' his hand, but just flat out choosing something, which is why you can't 'fail to find' a card.
if my opponent thoughtseies me, and there is a valid target in my hand, but they don't want me to discard it, must they still make me discard?
thanks.
