var KillAura = Java.type("net.ccbluex.liquidbounce.LiquidBounce").moduleManager.getModule(Java.type("net.ccbluex.liquidbounce.features.module.modules.combat.KillAura").class);
function ccbluex() {
    
	this.getName = function() {
        return "HypixelAutoblock"
    }

    this.getDescription = function() {
        return "a hypixel autoblock helper for killaura"
    }

    this.getCategory = function() {
        return "Fun"
    }

    this.onUpdate = function() {
      if(KillAura.target != null && !!(heldItem = mc.thePlayer.getHeldItem()) && heldItem.getItem() instanceof Java.type("net.minecraft.item.ItemSword")){
        mc.thePlayer.setItemInUse(mc.thePlayer.inventory.getCurrentItem(), 51213)
        }
      
    }
    this.onDisable = function() {
      mc.thePlayer.itemInUseCount = 0;
  
  }
  }


function onLoad() {}

function onEnable() {
    client = moduleManager.registerModule(ccbluex)
}

function onDisable() {
    moduleManager.unregisterModule(client)
}

but now no have any document about liquidscript on lb 1.12.2 b2
you can ask @Senk-Ju for help
or you need wait for lb cross version complete
