I was able to reproduce this on master.  The issue here is that the 'encrypted' setting needs to be a string rather than a boolean.

I have fixed the doc here:

The correct input parameters should be:
openshift_storageclass_parameters={'type': 'gp2', 'encrypted': 'false'}

Notice the 's on the 'false'.

When I changed the input parameters to be a string this issue was resolved.

Backport to 3.6 here:

Verify this bug with openshift-ansible-

Set the following options in ansible inventory file
openshift_storageclass_parameters={"type": "gp2", "encrypted": "false"}

After installation finished, check the default storageclass
[root@qe-gpei-test-bug-master-1 ~]# oc get storageclass
NAME            TYPE
gp2 (default)   kubernetes.io/gce-pd   
[root@qe-gpei-test-bug-master-1 ~]# oc describe storageclass gp2
Name:		gp2
IsDefaultClass:	Yes
Annotations:	storageclass.beta.kubernetes.io/is-default-class=true
Provisioner:	kubernetes.io/gce-pd
Parameters:	encrypted=false,type=gp2
Events:		<none>
