I am trying to that It will only harm the player If they touch a part that Isn't In a humanoid (?)

Hello Developers!

I made this script, this script will force the user to do a drop kick, the problem Is that I want to add a system where If they kick a wall they will get harmed, the problem Is that It will harm the player If they touch a humanoid (Like a NPC or Player) due to the humanoid having parts

Script:

local NPC = script.Parent

if script.Enabled == true then
    local PlayerInventory = game:GetService("Players"):GetPlayerFromCharacter(NPC)
    if PlayerInventory then
        local Tools = PlayerInventory.Backpack:GetChildren()
        for _, Tool in ipairs(Tools) do
            if Tool:IsA("Tool") then
                Tool.Parent = game:GetService("ReplicatedStorage").FolderThatContainsWeapons
            end
        end
        NPC:WaitForChild("Drop Kick").Parent = game:GetService("ReplicatedStorage").FolderThatContainsWeapons
    end
    script.Swoosh:Play()
    local DropKick = NPC.Humanoid:WaitForChild("Animator"):LoadAnimation(script.Kick)
    DropKick:Play()
    NPC.HumanoidRootPart.Anchored = true
    local TweenPropteries = {
        CFrame = NPC.HumanoidRootPart.CFrame + (NPC.HumanoidRootPart.CFrame.LookVector*35)
    }
    local Tweeninfo = TweenInfo.new(
        1,
        Enum.EasingStyle.Cubic,
        Enum.EasingDirection.InOut,
        0,
        false,
        0
    )
    local Tween = game:GetService("TweenService"):Create(NPC.HumanoidRootPart,Tweeninfo,TweenPropteries)
    Tween:Play()
    local Hits = {}
    NPC["Left Leg"].Touched:Connect(function(hit)
        local Character = hit:FindFirstAncestorWhichIsA("Model")
        local Humanoid = Character and Character:FindFirstChildWhichIsA("Humanoid")
        local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
        if Player then
            local player1 = game.Players:GetPlayerFromCharacter(hit.Parent)
            local player2 = game.Players:GetPlayerFromCharacter(NPC)

            if (player1 ~= nil) and (player2 ~= nil) then
                local humanoid = (player1.Character or player1.CharacterAdded:Wait()):FindFirstChildWhichIsA("Humanoid")
