Hello korkyk,
Thank you for providing all the details of the issue you are experiencing. I found some steps you can take.
To delete the app from iTunes, follow these steps without your iPhone connected to the computer:
Apps>Mac or PC
Before you delete, find out if you'll be able to download the app you deleted again (it depends on where you live).
- Launch iTunes.
- From the Library pop-up menu, choose Apps.
- Click the app you want to delete.
- Press the Delete on your keyboard.

You won't be able to delete the purchase from the Apple ID, but you can hide the purchase:
To hide your purchases
- Open iTunes on your Mac or PC.
- From the Store menu, choose Store > Sign In, and then enter your Apple ID and password.
- Go to the iTunes Store.
- Click Purchased from the Quick Links section on the right side of the iTunes Store.
- Choose a content type by clicking on Music, TV Shows, Apps, or Books from top.
- Hover your cursor over the item you want to hide.
- You will see an "X" either to the right or left top corner of the item.
- Click the "X" to hide that item. A confirmation dialog will appear once you click the "X."
