bash compare variable and variable + string

I have a small bash script to do some AWS CLI stuff. I am having issues with line 18 as I need to compare function1 =! (function2 && string) specifically

if [ "$(state)" ] != [ "$(task_name)" && "RUNNING" ]

see below;

#!/bin/bash

region="eu-west-1"
cluster="mis-core-dev"

## Get task name, state and check against "RUNNING"
task_name () {
  aws ecs describe-tasks --region ${region} --cluster ${cluster} --tasks "$task" --query 'tasks[].containers[].name' --output text
}
state () {
  aws ecs describe-tasks --region ${region} --cluster ${cluster} --tasks "$task" --query 'tasks[].containers[].[name, lastStatus]' --output text
}

## Get Task names from Cluster
task_status () {
  mapfile -t tasksInCluster < <(aws ecs list-tasks --region ${region} --cluster ${cluster} | jq -r '.taskArns[]')
  for task in "${tasksInCluster[@]}"; do
      if [ "$(state)" ] != [ "$(task_name)" && "RUNNING" ] 
      then
        echo "$(task_name)" "NOT RUNNING!"
        exit 1
      else
        state
      fi
  done
}

task_status

I am trying to aviod using jq as I want to keep dependencies to a minimum
