Thanks.
Required permits only boolean values- true or false. I see in this case you are passing a string that is not valid and hence the error.
You could try something like below
Email: <apex:inputField value="{!Book__c.My_Email__c}" required="{!IF(CONTAINS(Book__c.Country__c,"USA"),"true","false")}"/>
<apex:inputField value="{!Case.field2__c}" rendered="{!Case.Picklist__c=='Option 2'}" required="{!Case.Picklist__c=='Option 2'}"/>

But syntax is correct as per document look below
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_fieldsets_describe.htm
I checked the documentation and the syntax has an OR() which returns a boolean value too.
<apex:inputField value="{!merch[f.fieldPath]}"
required="{!OR(f.required, f.dbrequired)}"/>
OR() Determines if expressions are true or false. Returns TRUE if any expression is true. Returns FALSE if all expressions are false.
Formula Field Example:
IF(OR(ISPICKVAL(Priority, "High"), ISPICKVAL(Status, "New")), ROUND(NOW()-CreatedDate, 0), null)
This formula returns the number of days a case has been open if the Status is new or the Priority is high. If the case was opened today, this field displays a zero.
