I disagree with Harley_35 a timming belt failure would not cause a connecting rod to let go of the crank or the piston, timming belt failure will cause bent/broken valves, valve guides, camshaft, followers all the valve train, or damage to pistons or head.
the con rods generally only gives trouble after the big end bearing goes through lack of oil, or a bolt lets go, are you sure it's a con rod cam through the sump? at this stage i would have to say no to your question

I would not think so unless it dropped a valve and then the con rod broke under the stress , but that is unlikely the usual reason for a con rod coming adrift is a badly worn out big end bearing causing so much vibration that the securing con rod bolts came adrift, that can be checked if any of the valve gear is badly damaged then the workmanship is to blame . the reason for that is that a con rod coming adrift would not normally affect the valve gear. have the cylinder head taken of by an independent,good luck

Timing belt tension can not make a rod go through a block neither can a out of time belt. But if there was debris allowed to get in the pan whe the work was done it would be possible to have a bearing problem shortly after work was done

timing belt failure of any kind will not cause a con rod to let go, this is generally the result of bearing siezure or the bearing cap bolts breaking or coming lose (big end bearings).the bearings sieze because of a lack of oil or a faulty oil pump.

If a rod is out of bed it is a sure fire stress fatigue or bolt failure.Usual reasons for these are low oil pressure causing bearing failure & higher temps changing metallurgy &/or continual exssesive high revs?

yes the belt may not have been tightened or the tension could have been bad and not replaced causing the belt to jump time and thus the rod going .

no sounds like you ran low on oil or water
