I think the plans will be to go without a striker signing as I have seen Klopp using Carvalho, Jota and Gakpo at this position earlier. So I don't think they are *actually* looking for another striker at the moment. I think it likely would be Diaz-Gakpo-Salah for Liverpool leading the attacks and maybe Klopp plans to rotate from matches to matches. Also it would be hard currently for Liverpool to actually sell Darwin Nunez and they are not the type of club to sell someone that was brought for a huge fee and take a loss, so I think Nunez will be given fair amount of chances next season as well to develop and showcase his talent. Earlier Klopp also defended the player when fans doubted about his finishing skills, so hopefully Nunez can really show that he was all worth the money Liverpool spent on him.
I think there is no dire need for Liverpool to get a striker but even if they are then I think they are looking for backup player as a striker. So far their main focus has been on midfield in this transfer window.
