I'm very sorry to hear that happened to her. Still, the same methods mentioned in reversing T2D are also very effective in managing T1D and allowing such ones to live a much happier and long life. T1D is quite rare in comparison to T2D. I did miss the sentence where the AI mentions reversing T2D specifically, though it started off in a way that confused me as it wasn't relevant to the thread's focus of T2D.
I understand that not all autoimmune conditions can be reversed over time even when maintaining strict habits due to significant organ damage, I live with some myself that would come back if I returned to my old diet. I mentioned one case of T1D, but there are now many such individuals keeping their T1D under control with very low levels of exogenous insulin and non-diabetic blood levels. Here is what another AI references about managing it specifically with the same methods many have shared regarding T2D, along with the case report for the second:
"Long-Term (10-Year) Ketogenic Diet Study: A notable case report followed a patient with T1D who adhered to a strict ketogenic diet (\le50\text{ g} of carbohydrates per day) for 10 years (Koutnik et al., 2024). The patient achieved exceptional glycemic control with an HbA1c of 5.5% and a continuous glucose monitoring (CGM) time-in-range of 90%, all while experiencing a 43% reduction in daily insulin requirements. Crucially, the 10-year follow-up showed no adverse effects on kidney function, thyroid function, or bone mineral density, though LDL cholesterol did increase (Koutnik et al., 2024)."
(as I've mentioned, studies now show that a proper ketogenic diet is cardio-protective and the high LDL has no merit on atherosclerosis over time)
"Adult Management Case: Another case report followed a male in his 20s who slowly tapered down to a strict ketogenic diet (Gardemann et al., 2023). His diabetes biomarkers improved to the point of hitting the official non-diabetic range, his overall quality of life improved, and his total daily insulin requirements dropped significantly by 70%."
Here is the second's case study:

Note some of the very positive benefits and absence of adverse events that can be maintained in spite of T1D if you stick with it:
"It could even be argued that the patient is less prone to the dangers of diabetic ketoacidosis as his low glycemic variability stops blood sugar levels exceeding certain values, while diabetics following the standard approach show higher glycemic variability (Fig. 5). During the reported timeframe, the patient did not suffer from any acute illness. During the follow-up period, there was not a single incidence of severe hypoglycemia which has remained till today. There was also no incidence of ketoacidosis. Arguably, the most important change seen from this treatment was the significant increase in the quality of life of the patient. Due to the extreme reduction of blood glucose fluctuations and reduced HbA1c values, the patient reported more energy, clearer thought, the ability to focus better, decreased hunger urgency and the overall feeling of greater safety and security in the management of his disease. We have to keep in mind that such a diet needs to be followed for the rest of the patient’s life in order to achieve that tight glycemic control. Transitioning to a ketogenic diet may initially appear to be limiting from the outsider’s perspective but once the dietary commitment is consistently adhered to, people report high levels of satisfaction and satiety from protein and fat-focused meals. People following a ketogenic diet need to plan their meals when eating outside of the home. The beginning of this diet seems to be especially difficult for most people as they experience carbohydrate withdrawal and tend to crave sweets and carbohydrates."
