untested:
for kid in kids:
try:
if eval("kid.%s" % filt):
setattr(kid, prop, val)
except:
pass
if recurse:
try:
kid.setAll(prop, val, recurse=recurse, filt=filt)
except:
pass
I think this will be the minimum number of lines of code in any case, but I am
not sure how try/except:pass compars to if hasattr() in terms of speed, so it
may be that if there are many cases that trigger the except it will be slower.

eww. relying on implementation details. bad. not sure what good is.
guessing
eval("kid.%s" % filt) needs to be rewritten to handle your case.
This is better, but kinda klunky:
filt= "%(o)s.property1 == val1 and %(o)s.property2 == val2 and %(o)s.property3"
ok = eval( filt % {'o':'kid'} )
