the first problem here is the bad specification of the trim depth (10mm) with tiles that are only 3mm thick. this means that the adhesive thickness will be 7mm! A ready mixed adhesive (Dispersion type) sets by loosing moisture which it can't through glass tiles and so moisture can only be lost through the joints and will have taken ages ( a reason that you would avoid using a dispersion adhesive with medium/large glass tiles even at the correct (maximum 3mm usually) thickness). A modified cement based adhesive sets by chemical reaction and so doesn't need to dry out to harden and is hence more often specified with glass tiles but then again it should only be used on walls with a thin bed (~3mm) of adhesive. When an adhesive sets it creates a strong pulling force on the tiles which is sufficient to visibly bend large tiles when thicker beds of adhesive are encountered (eg on uneven floors). With 3mm thick glass tiles on a 7mm bed of adhesive I think that you are likely to be seeing the effect of this pulling force breaking the tiles especially in the area around the hob where additional heat induced stresses will also be present.
If wanting to fit thin tiles with a thick trim as in this instance then rather than bed out the tiles with thick adhesive a thin tile backer board (eg 4mm) should have been fixed to the walls before the tiles but after the trim had been fitted. Personnaly I would also want some recommendation from the tile manufacturer as to how to fit them as at 3mm thick they are outside of my comfort zone.
The type of insurance that most tradesmen have is public liability which covers things like accidental damage. Some may have additional product liability which will cover them for things that they are buying in and selling on to the customer. I dont think many (at tradesmen level) will have external insurance to cover their own workmanship but i may be corrected on this!
