A few thoughts about this:-
Your tradesman obviously doesn't understand the need to match the size of any replacement beading to the original (and for that matter the advisibility of cleaning off any labels, pencil marks, etc
as well as the need to prime or stain any "raw" timber before installation). Original (old) glazing often has quite delicate mouldings which simply cannot be reproduced in timber (by machining) hence why putty still has its' uses
Your man really doesn't have a clue how to cut mitre joints which are tight and clean. That should be a "stock in trade" skill for a carpenter or glazier. No excuses
He is also a bit handy swinging a hammer (badly). Now we all have accidents from time to time, but surely if you dent or abrade work you need to correct your error? (techniques: 2-pack filler and some judicious machine sanding on painted work, a damp cloth and a hot iron on clear lacquered work - both will minimise how bad the damage looks). As to cracks, etc - well they are often unavoidable on old windows or panelling and when I do sash window refurbs I always state catagorically before commencing that in 80 to 90% of jobs the window is going to need to have cracks stopped and to be repainted. So your cracked paintwork is probably unavoidable, in at least some of those cases
TBH I am on a combination of conservation work and new installs on a listed building at the moment. My multitool is probably one of the handiest pieces of kit I have in my site kit when I am refurbishing/renovating, but there are times when it shouldn't be used, or at least it needs to be used with extreme caution. Things like chips, cracks bruises, etc are all relatively minor issues which he should have known the fixes for - and applied them. But his inability to cut and fit mitres and the slovenly way he installs stuff is what really gets me. Yes, a level of damage is to be expected, but surely it's his job to correct his own errors and any minor damage and not leave it up to some hapless painter and decorator?

....am i being unreasonable? He removed the old glass with a multi tool & blade and hammer so I can understand how the damage has happened. Everyone else said they would have simply used a sharp chisel to remove the old putty, may have taken longer, but it wouldn’t have caused as much damage.
No, not at all. In fact there is a specific, relatively cheap tool made for the job of putty removal which every glazier should carry in his kit, the
leather handled hacking knife:
Because it is used sideways on to the glass there is less chance of damaging the glazing beads than if you use a standard bench chisel. I think I still have mine somewhere - and I'm a chippy
