You should initialize the ItemsViewModel in the parent Activity or Fragment:

private val viewModel by viewModels<ItemsViewModel>()

Then, instead of passing it directly to the ListAdapter declare a custom click listener and use that as parameter:

// Add a parameter in the adapter
class ListAdapter(
    private val clickListener: ListClickListener
) : RecyclerView.Adapter<ListAdapter.MyViewHolder>() {

    private var itemsList = emptyList<Item>()
    private lateinit var item: Item

    class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        return MyViewHolder(
            LayoutInflater.from(parent.context).inflate(R.layout.item_row_layout, parent, false)
        )
    }

    override fun getItemCount(): Int {
        return itemsList.size
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        item = itemsList.get(position)
        //always remember this technique to save the values in val type
        val currentItem = itemsList[position]
        holder.itemView.itemNameTV.text = currentItem.itemName.toString()
        holder.itemView.itemCodeTV.text = currentItem.itemCode.toString()
        holder.itemView.itemCategoryTV.text = currentItem.itemCategory.toString()
        holder.itemView.itemDescriptionTV.text = currentItem.itemDescription.toString()
        holder.itemView.itemSellingPriceTV.text = currentItem.itemSellingPrice.toString()
        holder.itemView.itemStockTV.text = currentItem.itemStock.toString()
        holder.itemView.deleteItem.setOnClickListener {
            val itName = holder.itemView.itemNameTV.text.toString()
            val itCode = holder.itemView.itemCodeTV.text.toString()
            val itCategory = holder.itemView.itemCategoryTV.text.toString()
            val itDescription = holder.itemView.itemDescriptionTV.text.toString()
            val itSellingPrice = holder.itemView.itemSellingPriceTV.text.toString()
            val itStock = holder.itemView.itemStockTV.text.toString()
            val itime = Item(0, itName, itCode, itCategory, itSellingPrice, itStock, itDescription)
            // Call the click listener
            clickListener.onClick(iitem)
        }
    }

    fun setData(item: List<Item>) {
        this.itemsList = item
        notifyDataSetChanged()

    }
}

// Click listener class
class ListClickListener(val clickListener: (item: Item) -> Unit) {
    fun onClick(item: Item) = clickListener(item)
}

Finally, declare your ListAdapter in the parent Activity or Fragment with:

val adapter = ListAdapter(ListClickListener { item -> 
    viewModel.deleteItem(item)
})
