You're conflating trying to sign strikers with trying to sign replacements. They wanted Mbuemo, Cunha, Delap, Pedro, Ekitike before Liverpool overtly made their interest known as they have 1 senior striker. They haven't stated a price, they have told Liverpool that they won't sell him (the reports at the bid were he wasn't for sale and Liverpool won't bid again...) and tried to get him to sign an improved contract with a release clause next year. They made him train elsewhere as he made a point of training alone at Sociedad rather than join the tour and he clearly doesn't want to be part of the group - eg it's him driving the division, not the club.
They may sell him if they feel it's untenable to move forward with him (a mistake considering their transfer window) and Liverpool meet whatever valuation they have, but it's not how you framed it
