Fantastic post. Great job Martin Janiczek! Fellow T1D here. Please keep posting because it is useful and interesting! I am a programmer and more glad to help you in any way with databases, SQL, Python, R, C#.

Resources that helped me achieve excellent control of my type 1 diabetes. My TIR is 95-100% and lowered my A1C from 11.9 to 4.1 (not low carb, I’m high carb in fact):

Fat and protein in meals require insulin 1-2 hours after eating via extend bolus (aka temp basal). Learn how to post-bolus (give yourself insulin AFTER meals) “Fat-Protein Units” (FPU).

Fat x .09 x 8 ÷ I:C = units of insulin Protein x .04 x 8 ÷ I:C = units of insulin

Sum both. Then dose insulin as a temp basal (extended bolus) over n-hours per the Warsaw Method time schedule linked below.

And continue to pre-bolus for carbs like usual 15-30 minutes before you eat (data driven approach is pre-bolus and eat meal AFTER blood glucose values on CGM trend down for 3-4 consecutive readings)

Starting point to determine your insulin-to-carbohydrate ratio: 300 ÷ Total Daily Insulin Dose = 1 unit insulin covers n-grams of carbohydrate

There is no path out for Type 1. However, the amount of insulin needed in greatly impacted by diet and excercise. More specifically, how many carbs you ingest and the efficiency which your body utilizes insulin.
