Answer 1

I don't know what role the argument ["1","2","3"] should play, but apart from that, you can convert the object items from string to boolean using fromjson, then aggregate them appropriately, and use this result in a map(select(…)) clause to filter the input array.
Now, if you want to remove items
if at least one key is not "true"
meaning you want to keep only those that are entirely true, use the all aggregator:
jq 'map(select(map(fromjson) | all))'
[
{
"1": "true",
"2": "true",
"3": "true"
}
]

But if, as your desired output suggests, you want to remove those items that are entirely false, meaning to keep only those where there is at least one value which is true, use the any aggregator:
jq 'map(select(map(fromjson) | any))'
[
{
"1": "false",
"2": "true",
"3": "true"
},
{
"1": "true",
"2": "true",
"3": "true"
}
]
