There is another data flow there already., and a couple of other tasks.
is it OK to add another data flow to the package without precedence constraints as shown on the attached image?
The 'Parents Data' data flow has nothing to do with any other dataflows/tasks, and the new data flow can probably be added WITH a precedence constraint before or after any existing tasks.
Is it a bad practice not to connect data flow to other control flow items?
Or since it has been added the last it is assumed that the new data flow will be executed after other tasks have been completed?
Thank you!

Adding a dataflow without precedence constraints merely means that it will execute in parallel with other tasks which are not bound by precedence constraints.
If such parallelism works in your case, go ahead and do it – you may find that this provides a speed boost. But watch out for conflicts when using parallelism (eg, parallel tasks accessing the same file or table).
The absence of evidence is not evidence of absence.
