Since this is a Square forum you may have to ask this question in an Instagram Forum. I believe you need to buy your GTIN numbers from a GTIN provider to give your Business a Unigue GTIN prefix. Here is a link to some GTIN information:

You are also correct you can not legally just make up a GTIN because of accidentially using another companies GTIN. This is why Square lets you make up your own SKU or Stock Keeping Unit, which has fewer restrictions of a GTIN.
You may want to see if I.G. would let you use a SKU instead of the 14 digit GTIN number.
Costs for a GTIN can be expensive:
$30 each
If you only need a few GTINs, we license individual GTINs for a one-time fee of$30 each, with no annual renewal fee. When you license a GS1 US GTIN, your company is uniquely and exclusively identified as the owner of that number, and you get access to other GS1 US member benefits.
